Hi
I own the M80v3 and the HK 3490
Honestly, look at another two channel amp. Not really overly impressed. Think it maybe closer to 80w per channel. not much volumn at all, if I need to play a bit loud occassionally I am at +10db of a possible +15
When I had my Denon 3808 for comparison I was maybe -5bd to 0db
Anthem 225 is a better choice.

Anthem MRX520
M5HPv4
VP160HPv4
QS10v4
