The Swiss Digital Fuse Box and the Weakest Link


A Swiss Digital Fuse Box (SDFB for short) is a $395 device that replaces the generic $2 power fuse in high performance audio gear. Yes, you read that right. It is also potentially the most disruptive audiophile add-on since…what?…the subwoofer?… the power conditioner? Sorry, but your THC gummies don't qualify. So let us first consider... Read More »


Origin Live's Vinyl Accessories - Mat, Weight, and More.


About a year ago I put together a selection of analog tweaks under $50 (HERE)—a mix of DIY, off-label use of non-audio thingamajigs, and commercial offerings. Among the latter was Origin Live's cool little Cartridge Enabler. I described it as a gateway drug for the firm's spindle weight and platter mat (which uses the same... Read More »


Analog Tweaks, Tools, Tips, and Hacks-Under $50!


Analog is resurgent, what with newbies discovering turntables and seasoned audiophiles revisiting reissued vinyl from their ill-spent youth. Digital music is a much more convenient background for other activities, but playing records better rewards attention with involvement; bitsy will just never replace groovy in the listener's lexicon. Blame the pandemic: one can read similar stories... Read More »


The Parks Audio Puffin Phono Stage - Etc, Etc, Etc, Etc, Etc…


So why all the Etc's? Because, while nominally an affordable MM/MC phono stage, the Parks Audio Puffin incorporates a flock of features and functions simply unavailable in phono stages commanding ten times the asking price ($489 to $639 depending on options). OK, not at any price. But for starters, the Puffin does do the phono... Read More »


iFi's Stellar Nova and SupaNova Power Cords


My last foray in the fiefdom of iFi focused on fixing a pair of power problems that plague too many audio setups: ground loops and DC offset. The diminutive GND Defender and DC Blocker elegantly address that annoying rattle and hum—and at the most un-audio-extortionate prices. As I mentioned in that review HERE, the two... 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 »


Adventures In De-Crapification with the USBe Perfect


Hey Kids! It's 2021, and with no more pressure to have the US BeBest, let's all go play with the USBe Perfect! When the call came in, Georgia area code—caller unknown, I let it go straight to voicemail. Finally weeding out spam calls, I found—tucked between a Police Defense Fund plea and a faux breast...

Alt-USB Cables: The Missing Ear Candy


Yes, I know. It's traditional to cite recordings used in an equipment review (and illustrate them with the cover art), but featuring even some of the music that used to evaluate four very different USB cables meant the review would run far too long. Ultimately, I had to cut all the window dressing. You can... Read More »


ALT-USB: Cables Curious, Unique, Magic, and Lush


Seriously? A review of four idiosyncratic USB cables? Didn't some sage audio scribe opine back in the MP-3 days that USB meant "Usually Sounds Bad"? Well, audiophiles have since embraced first High-Res downloads, and then streaming services like Tidal and Qobuz. With the result that getting the best sound from file-based audio often depends on...

The iFi PowerStation AC Line Conditioner


Go back some 50 years, and the American audio scene involved an assortment of acronyms from around New England: off the top of my head, AR, ADS, APT, CSW, DBX, EAW, EPI, KLH, and NEAR come to mind, with the BAS (Boston Audio Society) and MIT providing cross-pollination. Oh, and there was one nasty four... Read More »


The D.BOB Digital BreakOut Box: SACD Lives!


You don't have to be an economist to appreciate that much of Western Civilization is the result of the perennial tug-of-war between progress and profit, the towline under tension too often being…quality. The once well-beaten path to Emerson's maker-of-a-better-mousetrap has long since grown over, the production of an adequate device for the purpose of trapping... Read More »


VALVET 2se Power Amplifier


OK. Given a world-wide pandemic, why are we reading (and writing) audio reviews? First, as Congreve pointed out, "musick hath charms to sooth a savage breast." Second, it's what we do, especially with time on our hands. Up until a few years ago, I was active buying / selling vintage and audiophile LPs on eBay.... Read More »


Synergistic Research PowerCell ONE Line Conditioner


Just a mere month ago, Audio Tourism looked like the next new thing. Given the continuing demise of brick-and-mortar retail salons, regional, national, and international audio shows were popping up all over—how brilliant was having a show in Florida in February, not in Miami, not in Orlando, and not during school vacation week? But then,... Read More »


Cables, Footers, and Fuses


So this is the time of year for returning unwanted gifts, breaking resolutions, and picking up a few Steel Band CDs in the Caribbean. It's also a time to reflect on past accomplishments and give credit where credit is due. I'm a very part-time reviewer here, and didn't offer up any PF Writers Choice awards... Read More »


Hack-a-Rack: An Equipment Stand for Audiophiles on a Budget from VTI


Yes, V-TEE-I. That is not a typo. VTI is not from New Jersey; they don't make turntables (although they support them nicely); as far as I know, the initials stand for something other than Virgo Taurus Industries. Actually, I had never heard of them until recently, myself. I was mulling the prospect of replacing my... Read More »


Spatial Audio Hologram M4 Triode Master Loudspeakers: Small Space, Big Sound!


I don't trust loudspeaker reviews. OK, you do realize you can't trust what you read in the paper, see in an advertisement, watch on cable news, hear on talk radio, or click on Facebook? Or anything on the Internet at all? Unless, a priori, you agree with the content, the trolls, or the known bias?... Read More »


Gold Note PH-10 Phono: EU EQ OK for US LPs?


Gang tackling is not usually part of the gameplan around team Positive Feedback, but if you are a fan of phono stages, you will note that I am the fourth reviewer here to get a chance to audition the Gold Note PH-10 (see HERE, HERE, and HERE). As my colleagues have ably pointed out, it... Read More »


A Few Afterthoughts on the 2017 Capital Audiofest


When it became apparent I would have to miss RMAF 2017 because of a schedule conflict involving a moving van, a ferry, and some fifty boxes of records (among other things), I took heart in knowing at least I had a fall-back. I cancelled my flights on Southwest and booked the American shuttle to D.C.... Read More »


The Revenge of Analog


The Revenge of Analog: Real Things and Why They Matter, by David Sax The morning of Black Friday, just two weeks and counting past a very bleak Wednesday, and still a bit drowsy from the previous day's over-indulgence, I opened the front door and stooped to pick up our copy of the NY Times. Instead... Read More »
