@jjss49 — unfortunately I haven’t heard any GaN or Purify amps. I’ve got a defunct McCormack DNA-0.5 Rev A amp I was planning on sending to Steve for repairs and/or upgrades (thinking it’s probably the dreaded and fatal input board failure given my unit’s age), but after reading the reviews of these new amps I’m rethinking that now. The Mini GaN 5 was one I was eyeing but looking to hear more real-world feedback before possibly trying one, so obviously I’d be very interested in your impressions especially since you’ve got the Audions as a reference for comparison. Anyway, that’s my story for now.
