Rocky Mountain Audio Fest 2014 • Hot Product

First things first: while this is, as the sign indicates, a PS Audio PerfectWave power amplifier, it's in prototype form and built on the chassis for another product. The finished amp won't look like this (and won't have a display area).

What we do know for sure is this: the 250Wpc PerfectWave is fully balanced. Its input stage features 6H23 Russian dual-triode tubes, with the output coming from an all-MOSFET circuit. It's a class-AB design with output into class A. When available in the first quarter of 2015, it will sell for around $7500. Industry veteran Bascom King did all of the design work.

At the RMAF, the prototype PerfectWave drove a celebrated vintage speaker: the Infinity IRS Beta, which its designer, Arnie Nudell, set up.
