If any audio product should be standard issue, the lowly record cleaner certainly qualifies for that status. If you play records, they need cleaning. If you buy new or used records, they need cleaning. Yes even new ones need a once over with a good old record cleaner. Of course I have talked to people... Read More »

I'll share a snippet from an email exchange with Alan Kafton, proprietor of audiodharma, the company that makes the Cable Cooker. The subject is the long anticipated, but now available, Ground Breaker adaptor set for the conditioning of power cables. Good morning, Alan I just finished cooking a pair of power cords. One PC used... Read More »

So, let me pick up where I left off in my last Audio Ramblings… As I had mentioned in the review of the Infigo cable, we have here the rather expensive switch and Ethernet cables from Ansuz, two items from Synergistic Research (the Black Box and the FEQ Carbon), and the Coherence Systems ADD-POWR Symphony...

Speaker isolators…for a turntable? Yes, according to the folks at IsoAcoustics, or at least their surprisingly comprehensive online product selector tool. I wasn't expecting to find my audiophile-unapproved, direct drive turntables in the drop-down box, but there they were. And at the top of their list showing recommended vibration control devices were the GAIA-III screw-on... Read More »

It's taken me more time (years) to get serious about a new rack than any other component I've ever bought. My room and system have been so cooperative that for the past few years I've spent more time listening and looking for new music rather than fret about components, cables, room treatments, or a rack....

Audiophiles are a compulsive bunch. They will try just about anything and everything when it comes to improving the sound of their systems. One very common recourse for mitigating this affliction is tweaking. Tweaking is a repetitive, at times even incessant activity where fine mechanical or electronic adjustments are made in attempts to achieve a... Read More »

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 »

Acoustic Revive is a Japanese company that was set up in 1997, run by Mr. Ken Ishiguro-san. It specializes in connectors and anti-vibration products, but also offers innovative devices, most often the brainchildren of the University of Tokyo. We are testing one of the company's products that filter ground interference—the RGC-24K. The artificial ground, or—as... Read More »

As mentioned in some of my recent reviews, I have really settled in on the basic building blocks in my current system. Click on my name above in red for a complete list and description. Even during the lockdown, I never thought twice about making any major changes. This despite plenty of time reading about... Read More »
