AudioQuest Noise-Stopper Caps


Stick around long enough and you get to witness the life cycle of a fad. Presently, the audiophile community has been riding herd on RFI, judging by the third-party Band-Aids proliferating on Audiogon and webzine talk. I believe the interest to be an offshoot from the prior focus on the electrical ground: after all, RFI... Read More »


A Brace of Buzz Busters from iFi - The GND Defender and DC Blocker


I've long been a fan of those wizards at iFi, especially the wonky folks tasked with widget warfare on hi-fi noise pollution. Although perhaps best known for their cost-effective DAC/Headphone amps, iFi has also issued a stream of USB and AC power iPurifiers and iDefenders to address audio problems both common and not so. Of... Read More »


Graceline L3 Cables


I love cables. I hate cables. There, I said it. Cables—from an audio perspective—are that step-brother no one really knows how to engage at the annual Thanksgiving bash. Everyone knows he's part of the family, everyone knows he generally has a nice guy image, but no one really knows how to properly befriend him. Let's... Read More »


Rockwell Amplifier by ampsandsound


For the last five weeks, I have had the opportunity to sit back and enjoy one of the best amplifiers I have heard in a long time. It all started when I got a phone call from the owner of ampsandsound, he said he had something new and special in the works. I was intrigued,... Read More »


Musician Monoceros Preamplifier


Thick aluminum casing, a dark anodized finish, microprocessor-controlled functions, and mysterious red lights on the faceplate could describe the latest generation of Cylon Centurion from the Battlestar Galactica science fiction series, or the newly released Monoceros preamplifier from Musician Audio. While Cylons are a Hollywood creation, this preamplifier (linestage) is the real deal, and is... Read More »


EAR's Phono Classic - A Classic Phono Stage


A friend is a connoisseur of many things in life. At the intermission of a concert, he was puzzled that the audience was clapping as the pianist had made so many mistakes—he performed professionally. He pushed aside a meal at the first bite because it wasn't worth the calories. As a counterpoint, the first time... Read More »


RSX Beyond Phono Cable with DIN Review: Part Two


I rarely revisit my complete reviews, but the RSX top-of-the-line Beyond phono cable with DIN connector has revealed state-of-the-art attributes that are stunning to this reviewer. In its RCA-terminated form, the cable from the legendary Roger Skoff was musically natural and neutral with a bullet. I was never able to truly discover what it did... Read More »

Intona 7054-x Galvanic Isolator


The last few years I've been pretty pleased with my system, so I've really not been considering any major changes. My current gaggle of components, cables, and room treatments works well in my somewhat difficult room, and delivers most of the passion of the music while usually keeping me happily engaged.  I even get to...

More from Fono Acustica: the Armónico Power Cables


Back when I went to public school, everyone took band. If you had no preference, they gave you whatever instrument needed players to fill a section—that's how a dented, silver trumpet wound up in my lap. Most of us consumed the hour by chilling out, with the exception of a small coterie of trumpet players... Read More »


Simaudio MOON 740P Preamplifier


I tend to be a believer in a less is more approach when it comes to my audio system; find a high end DAC like the Chord DAVE, and use it's outputs to drive the amplifier directly. In my experience putting anything between the DAC and the amplifier adds noise, colors the sound, and removes... Read More »

Dual Duty - Questyle CMA Twelve DAC / Headphone Amplifier


It's funny. As we move up through the echelons of the audio world, the pieces that produce our sonic magic become more and more singular in function. The jobs which devices perform move into larger and more separate boxes as if no component can do two things well at once. Stay in your lane. In... Read More »

Siltech Legend 880 Cables - When the Classic Becomes a Legend


For those Audiophiles that have been around a while, the name Siltech conjures images of high-end esoterica and rarified audiophile air. Edwin van der Kley Rynveld, an electrical engineer with very high level experience at Exxon and Phillips, acquired the company in 1992. Since the acquisition, Edwin has propelled Siltech into the ranks of the... Read More »


Hana SH Phono Cartridge


Did high output moving coil cartridges morph into some kind of oddball niche product when I wasn't paying attention? Despite the considerable press attention paid to the relatively new line of Hana cartridges, nearly all of it has focused on the low-output versions. The precious few reviews mentioning the high-output versions treated them as, at... Read More »
