I would probably avoid the Marantz 7706 in your case because your using Parasound amps, which are voiced slightly on the warm side anyways and don't have a very good high frequency response. You would lose too much resolution by going with the 7706. Don't get me wrong, the Marantz AV7706 is excellent, with excellent power supplies and analog stages, but it does soften and roll off the high frequencies.
With the Parasound, I would likely go with the Anthem AVM 70 to get the most resolution. It is possible the McIntosh might do very well here as well. It might be just very slightly more mellow in comparison with the Anthem, but I think the McIntosh might have the edge on the power supplies.
