Plug and play
Meredith Gabor shows off a Qv2 “harmonizer,” manufactured in Massachusetts by QRT and distributed by Nordost. The Qv2, which contains both passive and active components, is meant to be plugged into an available AC socket in the user’s listening room, as (electrically) close as possible to the system itself, and is claimed to effectively “clean up” the soundstage and improve detail and resolution. Qv2s, the effects of which are said to be cumulative, sell for $350 each.
