I have a NAIM Uniti Atom. I ran Vandersteen Treo CT in a fairly large room. Full range floor-stander 87 db. It now runs Apogee Centaur- Minor. The AB NAIM amps are imo noteworthy for being musical - certainly not dry or etched.!it is ROON ready and the NAIM app is quite stable and good. If you want more power and features move up the line w 2 models above the Atom,
best in music to you
