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 »

A power strip is simply a "splitter" of the power supply—it goes in with a single cable, and it goes out via several outputs/sockets. Acoustic Revive in Europe offers one model, featuring four sockets. We would like to present you the latest version called the Absolute. This is the first part of a two-part test.... Read More »

PS Audio has been steadily developing as a high-end manufacturer since 1974, despite the trading of leadership on various occasions. Paul McGowan, the "P," and Stan Warren, the "S," were the founding partners. Stan left in the early 80s to found Superfon. Paul would leave in the 90s to join Arnie Nudel, having a hand...

When I first spoke with Scot Markwell, US Distributor of Furutech products, at Elite Audio Video Distribution in LA, and a longtime colleague of, and setup man for, the late Harry Pearson, about the opportunity to review a full loom of Furutech flagship cables and passive power devices, I admit to being more than a...

Abundant availability of AC power is something we take for granted. The distribution of electrical power has been executed with a level of unprecedented success: no matter where we look, there's the good ol' AC power outlet staring at us. Unfortunately, what is delivered by that good ol' AC power outlet usually arrives seriously flawed.... Read More »

Trigger warning: This article claims that power cables can change the sound of an audio system. To me, a review of AudioQuest power products is necessarily an article about their designer, Garth Powell. I wish everybody who is considering a Niagara power conditioner or Storm Series power cables (and more so people who think it's... Read More »

If you ask five guys what's the best way to configure AC power for an audio system, you're likely to get five—or more—answers. Everything in audio is contentious; AC power delivery is no exception. At one point I was advised, "Every component needs a dedicated line, especially your amps if you're running monoblocks." The reasoning... Read More »

I do not know if you remember our interview with Daniel Břeizina, the editor-in-chief of the Czech portal HiFi-Voice.com, published in the previous High Fidelity edition (No. 159, read HERE). Just in case, let me remind you that when he was asked for advice for a beginner music lover and audiophile, he said that it... Read More »

Image courtesy of Tweek Geek Power conditioners are an essential part of a high fidelity audio system. The reproduction of musical sounds in our homes begins with AC power. Unfortunately, AC power is susceptible to all manner of electrical contamination that impedes audio components from sounding their best. Even dedicated sound rooms with independent wiring...

High end audio is one of those hobbies where there are a seemingly endless number of tweaks and refinements one can add to an existing stereo system, presumably to make it sound better. Who hasn't played around with isolation pucks or cables at some point or another? But often critics of audiophilia start out with... Read More »

Please be patient as I step you through some backstory. I reviewed the Synergistic Research PowerCell 10 UEF power conditioner back in October 2014. It made a tremendous impact on the overall sound of my system—all for the good! Other than a change in speakers, maybe more of an impact than any other single component at that point... Read More »

Acoustic Revive was founded in Japan in 1997 by Mr. Ken Ishiguro, who is the design genius behind the innovative and ultra-quality Acoustic Revive products. Like many hi-fi enthusiasts, Ken-san's interest in audio arose through his love for music as a youngster. Ken-san told me, "I was listening to the Beatles when I was fourteen... Read More »

Acoustic Revive RPC-1 Power Supply Conditioner The intrigue usually starts with a message from Yoshi-san or Elia-san from the MuSon Project in Osaka, Japan, who export Japanese audio exotica to The World. Every time I get a message from Messrs. Hontani I get pretty excited, because long experience has taught me that with their extremely... Read More »

Sometimes we come to the reality that a certain product in our system is not the be all and end all we thought it was. Take for instance the "built-in DAC". It is a great idea till that fast paced technology renders that chip obsolete. I have often thought that what I have my system plugged into was... Read More »

Power conditioning products, like the Spiritual Audio VX-12 under review here, are still one of the most esoteric high end audio products produced today. I say that because they contain some very intricate designs that are usually so proprietary, some of them are sealed from anyone being able to peek inside. I know that can be... Read More »

There's every probability you already have an opinion about audiophile tweaks and the folks who review them. Sometimes it seems like half the double-blindsters on the internet remain fixated on the original AudioPrism StopLight CD marker pen, so discussing any device from that company entails a certain incendiary risk-especially as Positive Feedback now features a...

I may have said this before, but I'll say it again… all of these amazing cables you have in your system (as beautifully constructed as they are) will not amount to much if you have garbage power coming into your room. This probably goes for 99% of you reading this where you don't have the... Read More »

I think we can all agree that, generally speaking, the thought of experiencing a new power supply or conditioning product is not quite as exciting as fresh new speakers and amplifiers. I mean, who really wants to spend all that money on electrical cords and outlets? Still, I have experienced several power cords and power... Read More »

One can wonder why so many people at certain age start using expression "I remember that..." more and more often. I can not not remember that several years ago whenever I came across such expression in a text it usually ignited at least some level of aversion towards obviously "advanced" age of its author. Why... Read More »
