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 »

Akiko Audio Speaker Improver


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 »


Tekton Design Perfect SET 15 Loudspeakers


This review has had probably the longest gestation period of any review I've ever done. I've had the Tekton Perfect SET 15 loudspeakers in my possession for three years already.

IsoAcoustics GAIA III Speaker Isolators


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.

Fifty years ago SAE hit the market with its first amplifier, the venerable MK 1. A 60-watt per channel affair that stunned the audio world and received rave reviews by none other than J.

With the New Record Doctor X, Your Vinyl Cleans Up Nicely!

Vera-Fi Audio's SnubWay Noise Defender: Taking Your Audio and Video to the Next Level


I'm constantly on social media, quite often for audio-related purposes. And I'd seen teasers for months highlighting the ongoing development of Vera-Fi Audio's SnubWay Noise Defender, or more simply, SnubWay. The posts seemed to mostly focus on different variations of the case design, with only snippets of information regarding the actual function of SnubWay. With... Read More »


Gingko Audio's Cloud22 Isolation Products


As many years as I have been in this hobby, within the last few I have become more and more intolerant of the exaggerated claims of expensive tweaks by some manufacturers.

A Follow-up on the Vanguard Caldera 10 Subwoofer: Dual Subs Now Equals Double the Fun!


My original review of the Vanguard Caldera 10 subwoofer earlier this year was nothing short of an all out rave, and deservedly so!

Puron Resolve RFI Eliminators


  In my recent review of the Puron AC Power Conditioners, I was struck by the abundance of amazing and relatively inexpensive enhancements available to substantially improve the performance of your audio and video systems. Those include devices and accessories of every make and manner that, based on their outward appearance, would seem incapable of... Read More »


XACT S1 Music Server


The brochure included with the XACT S1 music server hammered on the point again and again. Digital that doesn't sound like digital. More like vinyl. The single-minded focus caused me to reflect on the scene and our recent history. What began with Perfect Sound Forever in 1983 is now snubbed in 2024. The new standard... Read More »

Vanguard Scout Loudspeakers from Vera-Fi Audio


I've been reviewing a ton of LPs over the last few years, and to enhance my review process, I set up a dedicated, all-analog system in one of my audio rooms.
