Dneu2011 Posted March 26, 2021 Share Posted March 26, 2021 (edited) During the last year, I have spent a lot of time building Custom Nelson Pass Class A Amplifiers, preamplifiers, and headphone amps and I need to start selling them. The amps I have been building are all from boards I get directly from diyAudio.com. I have listened to push-pull tube amps, SET tube amps, vintage amps, and even high powered class D amps on my Klipsch Cornwall III's, but always find myself enjoying the Nelson Pass amps the most.
