Marantz is fine. I just think Denon and Onkyo have the best combination of performance and user friendliness of all the current offerings.
For Marantz, I suggest SR7002 THX® Select2 Surround Receiver
For Yamaha, I suggest RX-V1900 7.1 Channel Home Theater Receiver
Again, these are all great sounding for what they are - basically 7 amps in a box. Buy the one that looks the best on your shelf, has the most desired features or layout, cost the least or is most compatible with your current remote.
