As noted in the Speaker Thread, pick your speakers first and build around those.
i would not go with the P7 without the 105 as it has better DACs and analog section
NAD stuff is good.
Since you are looking for HT also, I'm guessing, suggest:
Marantz 8801 with ATI AT3005 (or AT2005) Oppo 103. Or
Denon 4520 with A31 (or AT3003) and 103.
Order ATI from ClassicAudioParts, talk to Jeff in sales. May need 20 amp circuit for AT3005.
