Wave Storm Reference BNC Cables and the Chord Dave I have heard many cables I have liked over the years, and have endorsed several of them throughout my time writing for Positive Feedback. However, I would never have called any of them essential. My recommendations were always wrapped within circumstances; if you have a system... Read More »

It is hard to imagine any human inhabitant of planet Earth whose life has not been negatively impacted by the current Covid-19 pandemic. However, amidst this dark cloud there are a few silver linings. One of them is the way it has impacted the listening habits of audiophiles. The feedback that I have received from... Read More »

One of the unsung perks of reviewing high-end gear is getting to travel without the discomfort of leaving home. When something new arrives, often even before the piece has settled in, I'll sit down for a taste and get the strong impression that the acoustic is unfamiliar, like maybe I've gone visiting another dude with...

I've had the same Linn LP12 turntable in my system for thirty-six years. Regular maintenance has kept it in tip-top condition. Of course it has had a few different cartridges over that time, but with one exception it is the same now as when I bought it in 1984. That one exception being replacing the... Read More »

High performance audio components have a variety of needs to reach their full potential, and one of the most critical requirements is being fed the cleanest AC current as possible. A typical audio system can sound quite respectable with a direct feed of AC current from the wall, however hobbyists that are striving to cross... Read More »

My power conditioner is an EQUI=CORE 300 by Core Power Technologies. Some time ago, the company's assets were acquired and renamed Core Power Technologies A/V by web-based audio retailer Underwood HiFi of Hawaii.

If you believe in RFI—no, let me start over. If you believe in science (since RFI is a measurable phenomenon), most likely you are doing something to address RFI. We have all been advised to get those darn wires off the floor. A dozen companies will be happy to sell you specialized lifts at prices... Read More »

A fairly common thread that runs through most audiophiles who are partial to vinyl rather than digital, is their penchant for tweaking.

How to think about Power Conditioning Power conditioning is an incredibly touchy subject and seems to divide the audiophile community as a whole.

Auditioning cartridges is a lot like wine tasting and shopping for televisions. You never know how good a glass of wine from a $100 bottle tastes compared to a $10 bottle until you've experience it for yourself. And you never truly appreciate the delta between TVs until you've seen them side by side at an... Read More »

When it comes to streamers, my point of view is simple: software is king. Good software can make a streamer, and bad software can break a streamer. For example, I have a streamer that sounds wonderful, however, it crashes at least once a listening session. For a time I tolerated these crashes, however, with no... Read More »

I have come across a few skeptics in the audiophile community who subscribe to the notion that footers do not make much of a difference to the performance of audio gear. To them, I love relating details of a historical sporting event where footers, or in this instance, shoes, made all the difference to the... Read More »
