For Your Consideration - The Flagship Synergistic Research Galileo Discovery USB Digital Cable


I have reviewed several brands of cables over the years, but more often than not, I always seem to come back to the Synergistic Research lineup for its superb sound and performance. When offered the opportunity to review some of their newer flagship digital cables, the timing could not be better. I discussed several options... Read More »

Audio Ramblings - Infigo's Sparkle Series USB Cable


So here I am after a few years off from writing about audio—and yes if I wanted to there is a LOT that I want to say, but that will be another time—and where am I heading… a USB cable from Infigo Audio, a rather expensive switch and Ethernet cables from Ansuz, two items from... 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...

JCAT Signature USB Cable


Alright, so the JCAT Signature USB cable is one of the better USB cables I have heard, and fits right into my group of favorites in terms of being across the board excellent. And while I have a lot of cables here, I have not heard all that is out there—nor do I have any... Read More »


Purist Audio Diamond Revision 30th Anniversary USB Cable and the Fern & Roby Maverick Phono Preamplifier


A few things on my mind here. Make that two things; digital and analog. Digital as in getting the bits from A to B (in this respect the Diamond Revision 30th Anniversary USB cable from Purist Audio Design - $2100 for the 1.5 meter I have here) and analog in getting the signal from A...

Wireworld Platinum Eclipse Cables


Wireworld Platinum Eclipse 8 My first high end aftermarket cable was the Wireworld Nano Eclipse headphone cable. It was reasonably priced, had a unique cable geometry, and sounded excellent. This early success caused me to buy other Wireworld products well before I became a reviewer. All of my power cables are Wireworld, and for a... Read More »

The Axios CU headphone cable ships in a hard case I have been on the hunt for the best headphone cable to pair with my Hifiman Susvara for the last six months or so. Every time I go to an audio show, I always see the Hifiman Susvara connected to amplifiers with a beautiful cable.... Read More »

Final Touch Audio Callisto USB Cable


I started several cable reviews towards the end of 2019. My lack of interest in cable reviews prior was due to disbelief that extremely high end cables, especially digital cables, would lead to improved sound quality. I also will be honest and say, even if these high end cables do provide a noticeable benefit, I... Read More »


Stage III Concepts Pulsec USB Cable


The other day I had one of those funny moments when I did something out of character. These used to be infrequent, but now that I'm retired from the day job, there are more. Should I be worried? Or does life get more amusing when you exit the rat race and it slows down? This... Read More »

STEALTH Ethernet and USB Cables


A Google search found the pugilists in their corners sparring over USB and Ethernet cables, just as they do over interconnects and speaker wires. Being very new to the music server scene, I somehow thought things would be different, that maybe we had gotten beyond that. It's irksome to me that so many in the... Read More »


Audio Ramblings and the Matrix Cables from Black Cat Cable


Okay, so let's cut to the chase, the Black Cat Matrix line of cables (specifically the 3202 interconnects, 3232 speaker cables, and the DIGIT USB) are exemplary. Stunningly good for the price. Competitive with cables I have here that cost several times the 3202 interconnect's $699.95 per meter, 3232 speaker cable's $649.95 per 1.5 meters,... Read More »


Synergistic Research Galileo SX Cables - A Suspension of Disbelief


Let's keep it simple and direct. The new Synergistic Research Galileo SX cables are the finest cables that I have used in my system.

Audio Ramblings and the Skogrand Beethoven USB Cable


Ah yes, the world of cables… well specifically the world of USB cables. A lot of controversy as to their audible impact, or perhaps not if one actually sat and listened with an open mind. In the past I have shared the thinking behind their designs and any potential impact on the music (HERE), and have reviewed... Read More »


Unique Innovation Technology Perfect Music Purifier USB Digital Cable


Ever since I discovered that all USB cables were very different musically, and needed to be selected with maximum care, I have been searching for the top USB wire for my digital server. Among the USB cables that I have tried, I have been most pleased with the WyWire USB, the Kubala-Sosna Emotion USB, and... Read More »


Kimber Kable Axios USB Cable: World Premier Review


Hot off the assembly line in Ogden, Utah, comes Ray Kimber's very latest thinking in USB cable design. With five other models listed, starting at $50, this tour-de-force design is a semi-affordable $900 for a meter.
