Hey guys, unless I missed it, this looks like the owner's thread. I just got my 6005 from FedEx this morning to replace my Onkyo 702 (needed HDMI, never have been truly happy with the sound). First impression from Onkyo to Marantz, no calibration/anything other than adjusting speaker size and crossover- ...sounded pretty damn similar, definitely was thinking I overpaid for the name vs going with another Onkyo. Front soundstage did sound wider though; swore I had my center on when I was just in stereo. Not bad, but was kinda bummed it wasn't a bigger difference.
After running Audyssey it's a whoooole 'nother story - I'm still listening to music, but I watched the NASA intro on the old DVE disc immediately before/after running the calibration. All I can say is holy crap! It's early yet, but wow. Just with the music, my Athena F2.2's are FINALLY giving me the "full" sound I never felt I could get out of my Onkyo. I am completely stumped as to the sounds coming out of my system WITHOUT my sub on right now (mdax - mid, Audyssey all on, PLII music + stereo modes). Like I said, it's early and I haven't played around with much of anything yet - then again, this is the best my speakers have ever sounded and I probably won't touch it for music. I'll have to see how it sounds with movies next and see how it sounds when my sub lights up there. I'm not sure how much of this is the Marantz and how much of it is the Audyssey (never experienced it before - I am now a believer!) Either way, I have never been happier with how music has sounded on my system.
Marantz 6005
Athena F2.2 - fronts
Athena C1.2 - center
Athena F1.1 - surrounds
Mirage S12 - sub
I am off to hook up my PS3 and watch my first ever Blu Ray w/ lossless sound!
ps - for anyone that has it, the Tron soundtrack by Daft Punk - 7 - Rinzler + 8 - The Game has Changed =

!!!
edit: after watching Iron Man 2 and Despicable Me, I'm VERY happy. This is probably the clearest voices have sounded (no "what did he say?'s" for about the first time ever) and the sound is just so much more... full. Again, I don't know how much is the Marantz and how much is simply adding Audyssey, but I don't really care - I'm happy

The neighbors? probably not so much...
