Concerned about vibrations in your home negatively impacting your vinyl listening experience? If you're like me, you want to extract every bit of performance out of your high fidelity music system, and eliminating unnecessary noise and vibrations is one way to do that.  In a previous system in a former home, I used A/V RoomService...

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 »

In Part 1 of this review, I had a great time listening to the awesome but temporarily incomplete Gingko VCS Toolkit, and I was looking forward to receiving the Cloud22 Bases to complete the review. When the bases did arrive I was intrigued to find that Vinh Vu also sent me the new Cloud22 wool... Read More »

I've been a fan of Gingko Audio's vibration control products for a long time. Way back in '08 (remember the sub-prime mortgage crisis?), I reviewed the Cloud 9 vibration control platform for my VPI turntable (HERE). Fast forward 14 years, and I'm still using it. Although I've replaced the rubber isolation balls, it still works... Read More »

I came to the Nordost QPOINT Synchronizers in a roundabout manner. My primary interest was their QSOURCE Linear Power Supply. After auditioning a couple of low-price linear power supplies for my ethernet streaming front-end and coming away unsatisfied, I turned my gaze higher and spied the QSOURCE LPS. It exceeded my expectations and the review... Read More »

As in days of olde when men strode forth to slay dragons (or chase windmills), the modern-day audiophile is on a crusade. This villain appeared relatively recently, coincident with the world economy's tectonic shift to the Information Age. As many have observed, Radio Frequency Interference wasn't an issue for audiophiles circa 1970. Nowadays, it might... Read More »

One of those wall-warts came with the Fidelizer EtherStream network switch I use for music streaming. These little switch-mode devices have known issues. It is not good for music streaming; even worse, it spews contagion throughout the electric grid. With the ethernet switch on, my primary sources were degraded: the CD transport sounded worse. I...

I am happy to tell you about a little device that will do things you might never imagine possible. It is something that feeds my restless pursuit of perfect sound. You might simply call it a phono stage. But that would be like a fairy tale with only the, "They lived happily ever after" ending.... Read More »

The highlight bout begins with King Resolution dancing in his corner taunting Bishop Musicality across the ring, both egged on by PR guys with stakes in the outcome. The handicappers lay odds on the King. Why? Because resolution trumps all in the audiophile arena. These bouts occur regularly in my sound room. While I love... Read More »

A fellow-traveler who delights in extracting the max from his gear relayed this narrative the other day. "When guys come over for a listen, they often comment they never heard XYZ gear sound this good. Why is that? I tell them it is the attention paid to the little things—like premium fuses, RFI noise stopper... Read More »

Competitive upgrade, the notion of "keeping up with the Joneses," was never my thing. For whatever reason, even as our income grew, we opt to maintain the same comfortable lifestyle, rather like Warren Buffet has famously chosen to live in the same modest abode for 63 years. (We're going on 40 in our apartment. The... Read More »
