Wave High Fidelity Storm Reference BNC Cables


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.

Audience frontRow powerChords


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...

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 »

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

Core Power Technologies Equi=Core 1800 MK2


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