I have the AV7005 with the MM8003 8 chanel amp. I am under the impression that MM7005 is just a 5 channel version of the MM8003. Anyways, I can tell you I am very happy with this combo for both 2 channel music and HT (I am about 90% HT to be honest). They also look "purdy" together. I am coming off a Denon 4810 which does not have HDMI 1.4. I also recently got a 65vt25 and for 3d purposes I wanted to be 3d ready with HDMI 1.4 equipment. I feel that the Marantz combo is a step up in sound quality over my previous Denon unit.
An 8 channel amp actually is exactly what I needed so I bought the combo. I have a 6.1 channel HT set-up and 2 deck speakers so it worked out perfectly. I would have bought the 5 channel Marantz Amp if that is how many speakers I needed to drive.
