Follow-up: Main Stream from Vera-Fi Audio, Now in the Digital Source System

Tom Gibbs — Fri, 02 Aug 2024 15:05:04 +0000

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 »

Main Stream Master Class Dynamic Parallel AC Line Conditioner from Vera-Fi Audio

Tom Gibbs — Mon, 15 Jul 2024 20:13:00 +0000

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 »

The Fuse Box, an Ice Box, and the Mixed Metal Arts - Further Rumination on the Swiss Digital Fuse Box

Bruce Kinch — Fri, 12 Jul 2024 22:00:02 +0000

Back in February's Issue 132 (HERE) I wrote about the remarkable improvement in my system from replacing a couple pricey audiophile fuses with first one, and then two Swiss Digital Fuse Boxes. At that time there remained a couple of unresolved issues—first was the impending arrival of a rhodium-plated tellurium copper "Super-Duper-Sluggo" (the actual metal... Read More »

Bella Sound Hana Power Conditioner

Will Wright — Fri, 28 Jun 2024 19:42:45 +0000

Fifteen or more years ago I purchased a John Curl/Jack Bybee Signature Pro power conditioner, and still use it to this day. The Signature Pro used two power cords, each one connected to a bank of four outlets, one bank labeled Digital and the other Analog. Each bank utilized three Bybee Quantum Purifiers. You may...

Tom Gibbs — Thu, 23 May 2024 23:34:54 +0000

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 »

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

Tom Gibbs — Thu, 18 Apr 2024 16:20:24 +0000

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 »

Juan C. Ayllon — Tue, 06 Feb 2024 18:03:50 +0000

We've all heard horror stories of stereos destroyed by electrical storms and events. Towards that end, many of us use surge protectors or power conditioners, and if you're like me, you take it a step further and when lightning is present, you unplug your system. Unfortunately, you can't always be there when a major surge... Read More »

Puron AC Power Conditioners, Now with Worldwide Distribution by HiFi House UK

Tom Gibbs — Sat, 03 Feb 2024 16:54:14 +0000

There are two recent observations I've made in high-end audio: 1) There are plenty of relatively inexpensive devices that can add significantly to your enjoyment of music and video playback, even if those devices might appear to be incapable of making a difference. Also, 2) The number of "audio enthusiasts" who dismiss the perceived benefits... Read More »

Image courtesy of Audio Sensibility I've been writing professional (i.e., paid) audio reviews for 12+ years. I've auditioned hundreds of different wires from audiophile cable companies and written dozens of power cord articles.

Dean Waters on the hardware: Thoughts on the RSX Technologies Power8™ AC Power Box

Dean Waters — Tue, 22 Aug 2023 00:52:35 +0000

The RSX Power8™ eight-outlet Power Box has one simple goal in life: Distribute power without getting in the way. In theory this would seem simple enough. In reality, this can be more complicated than one might imagine. As audio purists, we spend enormous resources sourcing just the right DACs, turntables, amps, interconnects—you name it. We...

Power conditioning is one of those topics that is considered a little divisive within the audiophile community. There are some who say power conditioning is not needed, there are some that say it makes sense, but it ultimately provides little value, and then there are some who say that it is incredibly important. Where I... Read More »

Linebacker SE Copper Passive Power Filter from PranaWire

Marshall Nack — Tue, 11 Apr 2023 15:32:36 +0000

When is enough, enough? That's a rhetorical question when posed to an audiophile, because in matters of the hi-end, we never cross the finish line. Just ask Joe Cohen, the proprietor and lead designer of PranaWire, for his take on the subject: "Common wisdom holds that there is a point beyond which continued effort and... Read More »

It was around the midpoint of my Hi-end audio journey when I heard my first passive power distributor and I can still recall the shock. At this time—I'm talking decades ago—the Hi-End embraced the philosophy less is more. Virtue lay in the fewest electronic devices and the shortest signal paths. Minimalism ruled. The goal of...

PS Audio Stellar PowerPlant 3

Will Wright — Fri, 27 Aug 2021 17:04:30 +0000

There was hum in my system! It was the dreaded 60 cycle hum. So was it caused by a faulty power supply, or a power transformer too close to a high gain amplifier? No, more likely the progenitor of this problem was electromagnetic coupling somewhere in the cabling. Experimentation narrowed my search for the source... Read More »
