I saw your post here
https://www.audiosciencereview.com/...efficient-speakers-100db-klipsch-horns.42233/ , which seemed to, perhaps rightly warn prospective LA90 power amp buyers of China-only based Topping's less than great customer support. But I see that you do have this amp, though presumably not used with your horn speakers. Any
stability problems? Unless your room is very large, against the safety of your hearing, would you risk using the LA90 with your >109db SPL/w/m horn speakers?
That amp is so damned tempting.

My room's 20 ft x 11 but empties into a small kitchen. There's a triangular ceiling over everything which peaks at 11 ft. -and because my average midrange band level @ 11 ft is ~ 58db. My sealed Altec 416-8B midwoofers will do ~ 90db at 100Hz cleanly; below that are my three Rythmik F12 sealed subs. I had hoped to build a 3.3 home theater system, using the Topping DM7 or Okto DAC 8 Pro feeding balanced inputs of low power amps like these.
I'm not a DIYer, so the neurochrome amps are not really an option for me. What about Schitt or other low power amps? I thought about this
