Note to Virginia 

Yes, Virginia, I'm still very much in love with vinyl and turntables. 

No, my passion for DSD and SACD do not mean that I have no room in my heart for LPs. And for open reel tapes, too. (Now there's romance for you.) 

As a matter of fact, dear child, the past year and a half has allowed me to get two turntables into my listening room, in addition to my fully tricked-out Linn LP-12: the SOTA Millennia with SME 4.5i tonearm, Cardas Neutral Reference Phono Cable, and Cardas Myrtle Heart MC cartridge, and the Walker Audio Proscenium system. Each takes a different approach to turntable playback; each will appeal to different listeners; each lives at a different price point. (My review of the Walker Proscenium Gold Signature turntable system will be published elsewhere in this issue, shortly after this review of the SOTA Millennia/SME/Cardas appears.) 

In my review of the Walker Proscenium Gold Signature system, you'll see my full venting of the trials and tribulations of sourcing reference grade turntables for review. There's no point in publishing that rant twice, much as I might want to. I'm just glad to say that I didn't have the sort of dead-end problems sourcing a system from SOTA that I experienced with other companies. After some very helpful preliminary conversations with Kirk and Donna Bodinet, the principals at SOTA, we finally agreed on a project involving their flagship Millennia turntable, including their implementation of a vacuum hold-down for LPs. This would give me their best turntable configuration as a platform for a suitable tonearm and MC cartridge.

Mating tonearm and cartridge …some useful considerations

That brought up the next question, the one that everyone in the market for at turntable has to decide before making a final decision: what tonearm and cartridge should be used with the SOTA?

Without digressing too far on the subject, it's important to understand that you can't simply toss any old cartridge on any old tonearm and assume a happy marriage. For example, some cartridges (like, say, one of the hefty Koetsu's) are heavy enough that some tonearms won't balance properly with them, and so can't handle them. Beyond that, and briefly, you have to consider the effective mass of the tonearm, the compliance of the cartridge, the effective weight of the cartridge and its mounting system, so that you can calculate the resonance frequency of a given tonearm/cartridge. Physics dictates that a spring-loaded (the cantilever of the cartridge and its associated compliance) mass (the combined effective weight of cartridge and tonearm, properly set up) will have a given resonance frequency. This resonance will be a point in the audio frequency spectrum that the tonearm and cartridge will exhibit a resonant spike or hump of several dB or more due to their mechanical synergy, which of course represents a major non-linearity in performance. This resonance is an enemy of fidelity in LP playback, and may be combated by various measures—the composition and dampening of the tonearm, for instance—but the natural physical tendency will still be present.

The most important thing to do is to check the resonance frequency of a given set of tonearm/cartridge parameters and make sure that it is placed in a zone of lesser audio impact. Where is that? We can answer that question by a simple process of elimination. If the resonance frequency hump is above 20Hz, it will actually become audible in many systems and to some ears; if it is 7-8Hz or less, it will boost turntable rumble/low frequency groove noise and the distortions thereof. Turntable gurus therefore look for tonearm/cartridge combinations that produce resonant frequencies of somewhere between 9Hz and 14Hz—too high to magnify rumble, too low to be audible.

The calculation of this frequency involves a formula, but fortunately for the math-wary, I have found a very helpful website that gives a good overview of resonance and an excellent online calculator for determining whether or not a given combination is in the "golden range" for resonance. Point your browser at http://www.mhsoft.nl/MySystem/rf.html, and plug in the requisite figures: effective tonearm mass, effective cartridge weight, fastener weight, and cartridge compliance (all of which should be available from the manufacturers or distributors), the click on the "Calculate" button. The resultant resonance frequency needs to be somewhere between about 9Hz and about 14Hz for you to have an optimum marriage of tonearm and cartridge. Hats off to a very useful site…this makes it easy.

Continuing, then: In our discussions, Kirk's first take on this was to try pairing the SOTA Millennia with the finely crafted Triplanar Precision tonearm (the Mk. VII). The Triplanar is a low-medium mass tonearm, at 11 grams. (Note that tonearms of 10 grams or less are generally considered to be "low mass," 11-25 grams constitutes the "medium mass" category, while anything over 25 grams is in the "high mass" group. The basic rule: modern low compliance MC's are normally mated with medium-to-high mass tonearms; high compliance cartridges should normally be mated with low mass tonearms.)

Kirk Bodinet at CES 2005 with the SOTA Millennia/SME IV.Vi/Cardas Neutral Reference Cable/Cardas Myrtle Silver Heart reviewed in this article.

To this we planned to add the Cardas Myrtle Silver Heart MC cartridge, which Cardas lists as having a weight of 9.5 grams, a tracking force of 1.8-2.0 grams, and a "dynamic compliance" of 15 μm/mN, which is in the "moderate" range; see http://www.cardas.com/content.php?area=products&content_id=7&pagestring=Accessories&product_id=58. (I should pause for another educational footnote here: cartridge compliance is generally sorted into "low compliance" at 5-10 μm/mN, "medium compliance" at 11-20 μm/mN, and "high compliance" at 21+ μm/mN, with "very high compliance" at 35Hz and above.) The Myrtle Silver Heart MC is itself a custom iteration, developed especially by George Cardas, using the well-respected Benz family, and highly prized for its detailed, yet musical presentation. This combination should mate well—a moderate compliance MC with a medium mass tonearm—with an approximate resonance frequency of 8.96Hz, an acceptable result.

The SME IV.Vi tonearm

Unfortunately, weeks after Kirk and I thought the project was set, Triplanar ran into problems with its distributor at that time, and had to withdraw from the project. So it was back to the drawing board for a tonearm to handle the Cardas Myrtle Silver Heart. Fortunately, Kirk had contacts over at Sumiko USA who were willing to ship him an SME IV.Vi tonearm, which would also do the trick. According to the Sumiko website (see http://www.sumikoaudio.net/sme/manuals/tonearms_seriesIV.VI.pdf), the IV.Vi has an effective mass of "10/11" grams and can handle cartridges in the 5-16 gram range, making it another good match for the Cardas. The resonance frequency on this match would be approximately 9Hz, also OK.

In order to expedite the review, Kirk did the mounting of the SME IV.Vi on a SOTA armboard at his end, and then shipped the turntable to me here in Portland for the assembly of the turntable and the mounting of the Cardas cable and cartridge at this end. PFO's Senior Technical Editor Jennifer Crock and her husband Michael Crock once again did yeoman's work for me, and assured that the Cardas was properly mounted and adjusted for the review project according to specification. Many thanks to them both for their expert help.

Once the turntable had been assembled, Jennifer, Michael and I shepherded the SOTA/SME/Cardas system upstairs and placed it. Since the SOTA turntable itself is somewhat wider than my Vibraplane could accommodate, the Millennia was put onto one of DJ Casser's very handy "The Shelf" carbon fiber platforms, which was in turn put onto my trusty-rusty Vibraplane. My rather long-in-the-tooth Target turntable stand provided the foundation. Walker Audio's truly amazing Velocitor provided line conditioning, with Silent Source Power Cables handling the electrons.

The E.A.R. 324 on Black Diamond Racing cones, placed on the middle shelf of my Target turntable rack; the SOTA Millennia is on a Vibraplane/Black Diamond Racing "The Shelf" stack, one layer up. Note the Walker Audio Velocitor which provided juice to the E.A.R. 324 via Silent Source power cables.

Once the turntable was in place, it was time to get the SOTA vacuum hold-down motor in place. (I'll address the function of this motor below, for those who aren't familiar with vacuum systems on turntables.) The key to placing vacuum motors of this kind is pretty simple: how noisy is the motor? Some vacuum motors are quieter than others; some listeners are very sensitive to even quiet units if the sound is constantly present during LP sessions. The sound of a vacuum motor can become a real irritant in that case, and the motor will need to be placed outside of the listening room, but close enough to the turntable for proper operation. None of us were familiar with the SOTA unit, so didn't know if it was whisper quiet or sounded like an aquarium pump on steroids. 

After some discussion, Jennifer, Michael and I decided to place it in the room on my left-most Michael Green rack, furthest away from the listening position and the turntable, but close enough to be used easily. We would assess the noise level later, and re-position it at need.

Meanwhile: don't forget the cartridge output and the phono amp!

Another very important aspect of turntable performance is the matching of MC output and loading at the phono amp. (I am not addressing moving magnet, or MM cartridges, in this article, since I do not use them.) Various MC cartridges have outputs that range from "low" (approximately .2mV - .3mV) to "medium" (approximately .4mV - .6mV). By comparison, your typical SACD or CD player usually outputs 2.0 Volts. To handle the amplification of such a tiny signal to a minimum 1.0 Volt threshold for proper use by your line-level preamp, you need to be sure that you have either a phono amp that is specifically designed for a given turntable system (e.g., the Linn Linto, or the Walker Audio Reference Phono Amp, Second Edition), a phono amp that is sensitive enough for the output signal, and is internally or externally configurable for a number of different possibilities (e.g., the E.A.R. 324, or the Manley Labs Steelhead, both of whom have inputs for either MC or MM use), or a step-up transformer that can hoist your signal far enough to feed your line pre properly.

Tim de Paravicini's superb E.A.R. 324 phono amp

Additionally, proper cartridge loading—the impedance of a given cartridge—must be dialed in for best performance. The loading of MC cartridges usually ranges from about 100 Ohms to 47K Ohms. Cardas recommends operating in the 500-47K Ohm range. (As a useful guide, Cardas notes that for the Cardas Myrtle Heart on a very quiet audio system can go to a 47K Ohm setting. Audio systems that are subject to noise should move to the 500-1.5K Ohm portion of the loading scale. This lower setting also applies if the cartridge is not yet broken in. My Linn Akiva, by comparison, likes 100 Ohms in my system pretty well.)

For this review, I used my E.A.R. 324 phono amp, a remarkable and versatile component with real world-class performance. Depending on the configuration set by the user, the E.A.R. 324 can provide up to a whopping 72dB of gain for MC's. The 324 is quiet, clean, and flawless in operation. (As a matter of fact, it's so good that I gave it a Brutus Award in 2004 and purchased the review sample; see my review in Issue 15 at https://positive-feedback.com/Issue15/324.htm.) With the 324 in place, I was sure of pulling everything possible out of the rather lowish .3mV output of the Cardas.

I plugged the Cardas Neutral Reference phono leads into the E.A.R. 324's Phono 1 input (MC), and set the loading at 40 Ohms. (Note that this loading is a transformer loading figure, and not a resistive loading. According to E.A.R., 40 Ohms on the 324 equates to a 500 Ohm resistive value, which was just fine for this project, since the Cardas MC was still low mileage.)

I was now ready to fire the SOTA up. But before reporting on the sound …another digression.

The SOTA approach to LP playback, and an introduction to the differences in the turntable arts…

The La Luce CS Centoventi, a belt-driven, non-suspended approach with pivoted tonearm, record clamp and no vacuum hold-down (image courtesy of Cardas Audio)

Different turntable designers have differing convictions about two other important aspects of turntable configuration: suspension, and how LPs should be handled on their turntable platters. Broadly speaking, turntables can be divided into designs with various takes on a suspended platter/drive chassis (e.g., the Linn LP-12, the SOTA Millennia, the Basis line, and the SME 30) and those without (e.g., either of the La Luce, the Clearaudio line, the Transrotor line, Redpoint Audio, Teres Audio, Galibier). If you have a non-suspended turntable, you have a very solid foundation that directly couples the turntable to its supporting shelf/stand. You'll generally deal with the nastiness of vibration by paying deep attention to the isolating properties of the platform/shelf system that you place a non-suspended design on (e.g., a Vibraplane).

The Linn LP-12, a direct-drive, suspended design with pivoted tonearm, no record clamp and no vacuum hold-down

Suspended models try to build such vibration isolation into the chassis/sub-chassis of the turntable itself, and usually (but not always …see the LP-12, for a classic example) add more vibration control with record clamps, to assure a firm purchase on the LP. Vigorous partisans exist for both approaches, and reference-grade implementations exist for either design path. (We have included photographs of various examples and combinations of these; these are by no means a comprehensive catalog, and are intended to be merely illustrative. You'll note the great variety of approaches even in this small gallery of images.)

There's also the question of whether or not a turntable uses some sort of system to bind the LP to the platter, thus increasing (in theory) the degree of control over the LP while it is in motion. Many turntables employ a record clamp to greater increase the purchase of the LP to the platter; others use vacuum system as well to flatten the LP; and some do neither, allowing the LP to simply rest on the platter (quite often using a turntable mat of some kind to dampen vibration).

The SOTA Millennia, another belt-driven, suspended design, featuring pivoted tonearm, record clamp and vacuum hold-down (image courtesy of SOTA)

Then one must consider the motor system used to drive the platter. Most fine turntables use belt-driven apparatus (or some variant, like the band drive of Galibier Design), or even silk-thread-driven approaches. This has the advantage of off-loading the mass and most of the vibration of the motor drive from the turntable itself, although the problem of thread/belt/band "bind and go" (traction and purchase on the platter, followed by slippage, followed by a repeat of the cycle), leading to non-linearities in the stability of speed control, remain a design challenge. The alternative is to use direct-drive motors, whose force is applied directly to the platter from underneath. This eliminates "bind and go," but also more or less directly couples the motor and its vibration to the platter, and places a premium on the linearity of the motor's application of energy. Both alternatives offer a collection of obstacles for the designer to overcome.

Regardless of the drive system chosen, one must also choose how the greater or lesser mass of the platter is to be suspended for minimum friction and wear and for maximum precision of platter rotation. Most designers do this with bearings of various composition (metals like zirconium; gemstones like sapphire), inverted or not, in a well of one kind of lubricant or another. Some few have opted to skip surface contact of metal or gemstone on metal and float their platters on some sort of "air bearing" (e.g., Walker Audio) or magnetics (e.g., the Platine Verdier, or the new prototype E.A.R. turntable by de Paravicini). As a general rule, the further one moves from metal/gemstones plus lubricant bearings to air or magnetics, the greater the engineering challenge, and the higher the consequent price. The closer one comes to the theoretical ideal of a "platter floating upon nothing in a vacuum," the nearer one approaches the ideal of a frictionless, completely decoupled propulsion/suspension system for the LP. Such a system, in theory, would produce the foundation and propulsion for the greatest purity of playback signal from the grooves of an LP.

Finally, one can design a turntable that uses a pivoted arm of the kind familiar to all of us, or use one form or another of a linear-tracking tonearm. Both have plusses and minuses. In theory, a linear tracking tonearm maintains a more consistently correct perpendicular relationship with the record groove, mimicking the geometry of the original cutting stylus used to cut the LP. Unfortunately, executing that simple sounding task is fraught with engineering challenges. One either has to use some sort of electro-mechanical servo control to provide tracking—which simply controls the degree of error—or has to provide an air bearing system to let the tonearm "float" with the cartridge's movement in the groove, thus minimizing drag and imbalance during playback. Both pose serious difficulties to overcome if one is to achieve correct groove geometry; few have done this successfully.

Most turntable designers have therefore gone the way of the venerable pivoted tonearm. There is a much wider array of available solutions, and dealing with the mounting and the logistics of support is generally easier. But the use of pivoted tonearms is no bed of roses, either. The challenges there include a multitude of tonearm bearing problems, dealing with the geometry of a more or less constant offset from the perpendicular with respect to the groove (and thus significant non-linearities across the surface of an LP), and minimizing the effects of that offset (e.g., anti-skate settings).

Fair warning: the esoterica of tonearms is enough to drive all but the most dedicated to the nearest bottle of aspirin, which is why the setup and support of many combinations is a declining audio art. The response of some manufacturers (e.g., Linn, SME, Walker Audio, Clearaudio) has therefore been to standardize the preferred configurations of tonearm and cartridge with their turntables as much as possible, to optimize performance and minimize support problems in the field.

I sympathize completely.

The Walker Audio Proscenium Gold Signature turntable system, a belt-driven, air-suspended system with air-bearing linear-tracking tonearm, record clamp, and no vacuum hold-down

End of digression, at last. Applying the above considerations to the SOTA Millennia, I can summarize its design as a belt-driven, inverted bearing, four-point suspended turntable for pivoted tonearms. It combines a light-moderate mass record clamp—the SOTA Reflex Clamp—with a vacuum hold-down system rated at 3.0" Hg (equaling approximately 1.47 psi) applied to a 15 pound platter. The total platform is of moderate weight, at 44 pounds, exclusive of the pump and motor assemblies, each at about 20 pounds.

The Millennia vacuum system represents the current peak of SOTA's design practice, and was reviewed as their reference-level design. The coupling of the Millennia with the SME IV.Vi and the Cardas Myrtle Silver Heart and Cardas Neutral Reference Cable represents a very rational mating of components—how would it perform?

The Sound

The first good news to report is that I was very impressed by the quietness of the vacuum hold-down pump that came with the SOTA Millenia. I had been concerned that I would have to move it immediately from its very convenient shelf to my media room next door. This was not impossible, but would have been a pain to do. No worries, though: the pump was so quiet that, at first, Jennifer, Michael and I actually though that it was broken. We didn't hear anything, so we turned the unit on and off a time or two, trying to diagnose the problem. Michael finally noticed that there was power to the turntable, and that the Millennia was working, the vacuum waiting for us to drop an LP on the platter. Even after LPs were in place, the SOTA system was almost imperceptible.

That, my friends, is quiet.

The platter of the Millennia has what looks like a mat in place, on first glance. Then you realize that it is a special material through which the vacuum is drawn, to hold down the record without harming its surface or grooves. At the rim of the platter is an upturned rubber gasket, providing the seal necessary to complete the vacuum's holding action. This is activated in the simplest manner possible: you put an LP on the platter, and within seconds the vacuum pulls the record flat on the rubber seal. There's an ingenious auto-sensor that detects the presence of an LP and activates the hold-down system, making this step fairly foolproof.

I found operating the Millennia to be very straightforward. You clean your LP or LPs, turn on the turntable vacuum, drop an LP in place, apply the SOTA Reflex Clamp, and then turn on the drive motor. You're ready to queue your record. It only took us a few minutes to get the feel of the SOTA system, even though my experience with vacuum hold-down turntables has been very limited, there being so few of them….

Before running out the turntable and settling in for a listen, Jennifer strobed it for speed accuracy, and double-checked the alignment and configuration of the stylus. Once we were satisfied that all was well, I took out one of my "run out the turntable" LPs, played it through a few times, then let the stylus play with the run-out groove overnight. Over the following couple of days, I ran several of my Classic Records RCA LSC's at the Millennia—the Respighi, Scheherazade, Witches Brew and the like—to exercise the cantilever and put some signal through the MC's magnets and the new Cardas phono cable. After a few days, the initial light congestion of sound began to wear off, and LP playback began to bloom. The moment was right: because my time for listening to this combination was relatively short, I sat down to begin my serious listening over the next several weeks.

The Linn Akiva cartridge, in fresco

Baseline: Notes on the Linn Akiva/Lingo II/Linn silver phono cable

The SOTA/SME/Cardas was different in presentation from what I was used to with my top o' Linn's line LP-12 system. Let me explain what I mean, since you have to know where I've been to understand where I'm going. The arrival of the Lingo II, the latest revision of the Akiva cartridge, and the Linn silver reference phono cable had changed the well known aural complexion of my LP-12 from a punchy, musical platform with lots of Art Dudley's PRAT (Pace, Rhythm And Timing) and a great "boogie factor"—what my good friend Scott Frankland had once correctly described as "always musical"—to a much more detailed, extended canvas. The new LP-12 still had a fine sense of the heart and drive of the music, but where the Arkiv/Cardas Golden Cross phono cable/Ekos/Lingo I had previously focused on a thumping great bass and excellence of musical rhythm, the Akiva/Ekos/Lingo II/Linn Silver extended the sense of spaciousness, presence, and three-dimensionality in a very noticeable way. 

It was almost as if Linn had made the deliberate decision to extend the upper frequencies and pursue greater transparency with their venerable LP-12. The Lingo II power supply certainly gave an increased sense of deep silence and rhythmic control, while the Akiva/Linn silver phono cable attained a kind of airiness in the upper ranges that explored new sonic ground for Linn. In all my years with my LP-12 …now up to 16 or 17 or so …this was one of the most significant improvements that I'd heard. (That Linn keeps coming up with great improvements like the Akiva and the Lingo II is one of the great long-running stories in fine audio.)

And this was the analogical sonic context that the SOTA Millennia/SME IV.Vi/Cardas Myrtle Silver Heart/Cardas Neutral Reference entered—a tough act to follow!

Back to the Chase!

Over several weeks I got a feeling for what this system offered. In the first place, and my first impression, was that the vital midrange was quite delicious. This is no surprise; George Cardas designed this cartridge, and nothing that George builds will ever sin against musicality. After passing through the brief slough of congestion that cartridges pass through during break-in, the Cardas bloomed and the midrange came into its own. Its character via the SME/Cardas Neutral Reference phono cable became clear to me. The tonal balance of the mids did not have the same slightly rich and luscious presentation that the Cardas Golden Cross cables provide; the "neutral" in Cardas' Neutral Reference designation is accurate. Instead, the SME/Cardas cable brought the cartridge back to a lightly cool sonic presentation, with the slightest emphasis on detail.

The SME arm seemed to synergize well with the Cardas and with the table; there was a firm sense of control and clarity. I heard no resonant nasties in the SOTA/SME combo, either in the table or in the tonearm. A minor point: tonearm students should note that the SME IV.Vi's dampened cueing is not as slow and elegant as that of the Linn Ekos; you have to be careful about how you drop the stylus into the groove. This is no problem, but something that you should be aware of.

The sense of rhythm was different with the SOTA Millennia system than I had been used to with the new LP-12. There is a definite sense of musical virtues I associated with the Cardas MC—tonal richness, top-to-bottom proportionality, rhythmic rightness—but also clearly a foundation of control in the Millennia/SME platform and the SOTA vacuum hold-down and record clamp, which tightened up the bass and brought a heightened emphasis to detail. (I think that some of the detail emphasis I was hearing might be attributable to the cable; those looking for more richness/warmth would likely find it simply by shifting to the Cardas Golden Cross on the phono cable.) The synergy between the musicality of the Cardas MC and the detail/control of the SOTA/SME created a dynamic balance between the two, and kept the listening experience at a neutral/very lightly cool place. (For Rick Gardner's brief notes on the Cardas Myrtle Silver Heart MC on a very different turntable, read his sidebar elsewhere in this issue.)

Throughout my sessions with it, the SOTA Millennia was flawless. It was quiet, and its vacuum hold-down system never intruded on my listening sessions at all. The vacuum handled every LP that I loaded, even a few that were not quite as flat as I would have liked, and the SOTA Reflex Clamp was straightforward in its operation, once you get the hang of it. (Jennifer Crock pointed out that you have to be firm in applying it in one definite movement, since the platter bearing doesn't appreciate the jitter of "on-again, off-again, what the heck am I doing?" clamping. Kirk at SOTA can give you some advice here.) No matter the LP, the Millennia handled it with ease, and never left me wishing that I was listening to something else. If my experience is indicative, the Millennia is certainly a well-behaved turntable. Those concerned about the complexities of a vacuum-based turntable system have nothing to fear.

Overall, I enjoyed my all-too-brief time with the SOTA Millennia/SME IV.Vi/Cardas turntable system. The combination proved to be musical, controlled, nicely detailed, and engaging. As I observed, listeners who prefer warmth or richness in their LP playback will want to look to the Cardas Golden Cross cable instead of the Neutral Reference, which should give them just the right touch of magic. SOTA's Millennia should provide a fine platform for other tonearms and MCs as well; heck, I'd love to hear it with a Graham, a Schroder, or a Moerch. Given the performance I observed, the Millennia would do exceptionally well.

I therefore awarded the SOTA Millennia/SME IV.Vi/Cardas Myrtle Silver Heart MC/Cardas Neutral Reference phono cable system Brutus Awards in 2004.
