FWIW- I decided to sell my 2 emotiva behemoths-(both XPA- Gen 1) (3 ch/200w-57lbs. and 5ch/200w-70lbs. amps) , as we are selling our house and downsizing.
I was happy with eh emotivas, they have been serving me for 10+ years, without incident.
I decide to try the aiyima A07 as it looked ideal for moving to a smaller abode.
I bought 1 to test on my main speakers, Gallo Classico cl-4's (4ohm, 92db).
They sounded quieter, better imaging and punchier bass. What a surprise, differences weren't subtle.
Bought 2 more to drive a classico 10" sub (dead plate amp, hooked up 1ch of an a07), my 2 rear speakers (classico cl-2's-90db-4 ohm) and the classico center channel ( 4ohm-92db)
No sense of less power and the system with 2-ch cd's and multi-channel sacd's sounds phenomenal.
Very happy camper. Highly recommended. (and my room is cooler too as a bonus)
