Albert, I can't speak to the Earthquake Cinenova Grande 7 since I have no experience with it.

I have, however, owned the Outlaw 7500 (same architecture and specs as the 7700, minus 2 channels) for several years now and been extremely pleased with it. It's comfortably driven my difficult to drive Martin Logans and been a very pleasant upgrade to the Yamaha receiver, bridged Classe CAV-75, and Outlaw 7125 that preceded it. I recommend the Outlaw 7500/7700.
