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 »

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.

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. For me to keep any A/C cable longer than a year or two, said cord must deliver either: a), state-of-the-art sound; or... Read More »

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.

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...

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 »

In order to achieve that quality, a power supply must be fed well, hence the plethora of aftermarket power cables and conditioners. The subject of this review, the Clarus Duet purports to...
