A lot of people favor Marantz but I find it harsh and bright sounding. Listen for yourself.
Fail. Except the last sentence, which if you do, you'll find that Marantz leans toward the warm side. I've never heard a "bright" Marantz component. I have an AV7704 in my main HT system and a KI-Pearl SACD player.
If you do go with a Marantz processor, search for a shootout between the 77XX series and 88XX. The bottom line was that everyone in the group was unable to detect any sonic differences between the two series, so unless you need some connections or features on the 88XX series that aren't included in the 77XX series, you're better off going with the 77XX unit.
