I've had a really good relationship with Norman Varney from AV RoomService for a couple of years now; his company manufactures a variety of products that are aimed at reducing airborne and other vibrational noises in your listening room. He also is heavily involved in custom listening and audiovisual room design and construction; his level... Read More »


The Magnepan Magneplanar LRS: So Much More Than Just a "Taste" of the High End


The Magneplanar LRS with stock stands attached 1973: William Michael Albert Broad sat at his desk at the Worthing High School for Boys with a particularly nasty scowl on his face. He'd just been handed his report card for the term, on which his chemistry teacher had scrawled the word "idle" across the unusually low... Read More »


Centrance Cerene dB Transparent Reference Headphones


I've owned a number of decent headphones over the course of my life as an audiophile, and I always generally have a couple of pairs on hand. Mostly for listening when my wife, Beth, has control of the television and has landed on HGTV or some insanely sick horror flick that I could care less... Read More »


ampsandsound Leeloo Mono Tube Amplifiers: Superior Single-Ended Triode Performance for Headphones and High-Efficiency Loudspeakers


I've owned a pair of Zu Audio Omens—the Dirty Weekend (DW) variety—for over five years now. Zu builds high-efficiency loudspeakers that employ 10-inch full range drivers and compression tweeters, with many of their models approaching 97dB per 1 watt input. During operation, the 10-inch drivers, which are custom-manufactured for Zu by Eminence in Kentucky, run... Read More »


Advanced Optical Streaming with the Sonore Signature Rendu SE System Optique


Since Adrian Lebena reached out to me three years ago with the offer to review Sonore's first product, the microRendu, a Sonore streamer has been in my system ever since. The microRendu was amazing—especially when paired with Sonore's Signature Linear Power Supply. It took my streaming experience—which previously had been restricted to bandwidth-limited and feature-limited... Read More »


AV RoomService Low Density EVPs: Now Providing Superior Isolation for Lightweight Components


Vibrations. They occur in every aspect of the listening room environment, whether that room is dedicated to the listening experience, or just happens to be your living room—or any other room where your audio equipment resides, for that matter. The problem is—even when you think you've taken the greatest precautions to prevent spurious vibrations from... Read More »


A New Reference in Electrical Power Conditioning: the ADD-Powr Sorcer X2


I've been detailing my experiences with my new home and new listening room over the last couple of years here at PF; a recent article in the last issue (HERE) chronicled my ongoing battles with a seemingly never-ending variety of sources of noise in the listening room. A room that, from the beginning, was designed... Read More »


DS Audio ST-50 Stylus Cleaner; Keeping Your Stylus – and the Message – Crystal Clear


There's a scene from The Godfather where Sonny, Michael, Tom Hagen, Tessio, and Clemenza are all sitting around, strategizing in the aftermath of the failed assassination attempt on Don Corleone. They're also concerned with the whereabouts of Luca Brasi, the family's ruthless hit man. Tessio then brings in a brown paper wrapped package and places... Read More »


Audioengine A2+ Wireless Powered Speakers


When I reviewed Audioengine's flagship HD6 speakers a few years back, I was absolutely smitten with their build quality and magnificent sound—especially with a hardwired connection to a good source. I so went on about the sound quality—finding it not at all unlike that of a good British mini-monitor—that, after the review, Brady Bargenquast of... Read More »


In Audio - as in Life - the More Things Change, the More They Remain the Same . . . or Do They?


I've just gotten in and installed a really cool review unit from ADD Powr (which stands for Algorithm Digital Defined Power), the Sorcer X2, which employs high-tech digital technology to enhance and condition either the dedicated electrical line servicing your audio equipment stack, or perhaps even your entire electrical system. The design is from Bill... Read More »


iFi AC iPurifier - Helping Improve Your Playback Experience by Reducing AC Power Noise


At my old place, I had a plethora of audio-related problems, not the least of which was with AC power. An early 80s house, it was reasonably well built, but almost everything in the home was contractor grade, and not everything employed the best construction practices. I first noticed I had an issue when my... Read More »


Hana SL Moving Coil Cartridge with the Musical Surroundings Phonomena II+ Phono Preamp with Linear Power Supply


I love the new world of digital file streaming; I love the convenience of accessing your entire music library at the touch of a few tablet buttons, and I love the fact that digital-to-analog conversion has reached a state of near perfection that early digital only hinted at. And with so many outstanding tools at... Read More »


Fiio Redefines Performance-to-Price With Three New Digital Audio Players


Yeah, yeah, I know, I'm rapidly developing a reputation as a Fiio fanboy. The thing is, I put a fair amount of effort into cultivating a relationship with them at a point when they were just really cracking into the North American market. And now, suddenly, they're responsible for a rapid-fire release of multiple product... Read More »


The Fiio FH-5 In-Ear Monitors, with the LC-4.4C Balanced Cable


When I first gained an awareness of Fiio as a company, I thought their product offerings were very reasonably-priced alternatives to the typical mega-buck audiophile choices available in personal portables and accessories. But I wasn't absolutely convinced that they could make the transition to a company that could meet consumer demands for the level of... Read More »


JPLAY Femto for Windows, and UPnP vs. DLNA in a Computer-based Music Server Setup


Marcin Ostapowicz of JPLAY contacted me a couple of months ago; JPLAY had just released the latest iteration of their superb computer-based music playing system, now billed as JPLAY Femto. Would I be interested in taking a listen? Of course, was the answer—JPLAY has definitely been my go-to software choice for making baseline comparisons between... Read More »


Zu Omen Tweeter and Capacitor Upgrade - A Stunning Improvement in Clarity


I've had the "Dirty Weekend" version of the Zu Audio Omens for almost five years now; retailing for right at $1K USD, they're the least expensive way to taste the Zu experience. Zu has a very liberal upgrade and trade-in policy; they're constantly improving the technology of the drivers and cabinets they employ. The "Dirty... Read More »


Wolfsong Audio to the Rescue!


A couple of weeks back, I arose on an otherwise unremarkable Sunday morning, had my coffee and checked my losing lottery numbers. I then proceeded downstairs to remove and replace the Hana EL cartridge that's been the recent mainstay of my analog playback system. The Hana SL (with its Shibata stylus) had recently arrived from... Read More »


AV RoomService EVPs (Equipment Vibration Protectors): Outstanding Equipment Isolation for Systems at Any Price Point


When this review offer came from Norman Varney's company, AV RoomService, Ltd., I knew Norman from the Facebook experience, and I knew that he worked with custom audio installations that appeared to me to be fairly high-end. He seemed to me to be a really nice, knowledgeable guy, and I enjoyed seeing photos of some... Read More »


The Fiio Q5 Portable Headphone Amplifier/DAC - Now With the New AM3B Amplifier Module


As Fiio continues their push into higher-performance personal portables (and into the US market!), they're releasing some technologically remarkable products that perform at a shockingly high level. And at price points that tend to be well below the cost of completing brands like AK, HiFiMan, and Sony. I'm continually impressed by the performance of the... Read More »
