I had the anthem 225 first with B&W 804 then Paradigm Prestige 85f neither of which made it break a sweat. I found it to be neutral amp , I guess it did what you want an integrated to do forget it was there. Sounds good at low levels and as loud as you can stand it. I would still have it but I moved to a small patio home and my listening room is now my living room so I wanted an amp with room correction so I sold for funds to buy a new amp. I will mention again there was a problem with the volume control moving on it's own and the only way to stop it was unplug it, anthem put out a firmware update that fixed it and I think it only applied to the first generation. Anthem sent me the update and I flashed mine, easy fix if needed.
