While browsing the photo gallery on the Node Audio website, I came across a group shot of five finely crafted, elegantly designed objects. They appeared to be variations on a theme, but what was the theme—what were they used for? Sometimes you come upon objects that grab hold of your attention, yet their purpose remains... Read More »

It seems a lifetime ago. For my side hustle as a mobile DJ, I honed my beat-matching and mixing skills with a pair of Technics 1200 turntables at home to apply on the road with a Pioneer CMX-3000 Dual DJ CD player, but after I married Belle in 2011, I sold my gear, reinvested the... Read More »

The Maestro himself! (Portrait and image processing by David W. Robinson) My LP life When writing audio reviews, reviewers are often called on to describe things we readily hear that aren't always easily quantifiable. We use adjectives like 'open,' 'free,' 'effortless,' 'relaxed,' etc. The list goes on and on. Every once in a while, we... Read More »

When Mark Schifter hooked me up with the first two devices from Vera-Fi Audio's new trio of power conditioning equipment, I simply wasn't prepared for the dramatic differences they made to my all-analog system. That system uses single-ended RCA connections throughout, and it had a couple of problem noise areas I couldn't seem to eliminate,... Read More »

In 2021, the Canadian company Reliable Corporation presented the Uberlight Flex lamp for audiophiles who use turntables. It had the shape of an elongated tube with LEDs attached to a flexible "neck." The company drew on its many years of experience in the production of lamps used to illuminate sewing machine workstations. On February 18th, the... Read More »

I was passionate about music in my youth. I lived for Rock & Roll. I had a good voice and, like many young men in that era, I started learning guitar and piano. When it was time for me to head off to college I had some choices to make. Earn my living on music... Read More »

I recently became aware of HumminGuru, a Hong Kong based company with a quite forward-looking perspective on the viability of vinyl. While reviewing their affordable and very effective ultrasonic record cleaning machines (HERE), I also discovered a couple of accessories that break new ground for LP spinners. As with their record cleaners, HumminGuru's only outlet... Read More »

Over the years I've worked on refining the sound in my listening room by both upgrading/changing components and adding room treatments. Not sure why, but the whole room treatment project always seemed like a separate component of the system. Corner treatments, absorptive panels, diffusers, and Argent Room Lenses, in addition to the occasional component and... Read More »

HumminGuru? Just another Tik-Tok #influencer, you'd think? No, it turns out HumminGuru is a Hong Kong-based firm focused on accessories for vinyl enthusiasts, from LP inner sleeves to ultrasonic record cleaning machines. Two actually, both functionally similar to the high-end audiophile approved $4-6K machines, but currently going for as little as $379 and $699. Not... Read More »

When my review for Vera-Fi Audio's Main Stream™ went live a few weeks ago, Vera-Fi mainman Mark Schifter was only able to supply me with a single device for evaluation. Which according to Mark was at that point the only alpha unit presently in the field! I was really keen to first check out its... Read More »

Early this year, Vera-Fi Audio main-man Mark Schifter messaged me to gauge my interest in a new product line he was then representing from Thai manufacturer Puron. I'd told Mark that even though I had a pair of AudioQuest Niagara Low Z, AC power conditioning units in place at the new home in South Carolina,... Read More »

In Chapter 15 of the Acoustic Revive Chronicles I'll be telling you about the new RTS-30 turntable mat, RHS-1 headshell, RHR-21 Helmholtz resonator, and the... Read More »

As I stated in my original review, the primary function of Vera-Fi Audio's Swiss Digital Fuse Box (SDFB) is to remove and replace the weakest link that existed in the device it's connected to. Which in my case was the main AC line fuse in my PrimaLuna EVO 300 tube integrated amplifier's power supply. Other... Read More »

Over my life as an audiophile, I've had three individual instances where I was absolutely certain beyond doubt that the consequences of my actions would in no time send me rocketing down the highway to high-end audio hell. The first came over a decade ago when I followed the advice I'd gotten from another audio... Read More »

Audiophile tweaks; you can either love them or hate them, but if you are a passionate audiophile, they are difficult to ignore. Sure, they can be controversial, and in a few cases, they can even be outright frauds with claims that border on the ludicrous. However, in my experience, if you look long and hard... Read More »

A while back I found myself the new custodian of some excellent prototype speakers. I'd heard the Communique floorstander at several Colorado Audio Society listening sessions and really enjoyed this speaker. Built by MG Audio Design, which was mainly a cable company at the time, (Positive Feedback's own Pete Davey reviewed their Planus speaker and... Read More »

As widely noted, for the second year in a row in 2023, vinyl record sales topped compact disc sales in the U.S.—this time by a whopping $43 million, or about six million more than total CD sales last year (popsci.com). This point recently hit home personally when my wife, Belle, said that her hipster boss... Read More »
