1. Oppo 93 is a good choice.
2. I do not know the AC M3 but the roomEQ in the Arcam 888 (an otherwise able performer) is cursory.
3. For 2 subs and roomEQ, you should consider only prepros with Audyssey MultEQ XT32 as it can handle two separate sub channels and none of the other built-in EQs can do this, afaik. That means either the Integra 80.2 or the Onkyo 5508 if you require XLR output.
