I recently had the chance to listen to the Axiom II/Walker passive stepped pre in my system, and thought it sounded better than my active tube preamp.
In researching it seems like the best quality passives are autoformers, and the Slagel based units seems to the best one, particularly the silver version.
Has anyone built/used one of these and can comment?
I need a balanced version, if anyone has one of these for sale, or would consider building me one with remote volume, or guiding me to build one, with my basic soldering skills.
Sources are the new PS Audio DSMKII, and Soundsmith Strain Gauge phono pre, going to BHK300 mono amps.
Thanks.
