Sound of AVR vs. separates


Hey guys!

Probably a silly question - but I am thinking of swapping my Marantz 7011 to the 8802 - I'm currently using a Krell Chorus 5200 amplifier. I have thought about waiting a bit and going to a McIntosh or something similar...

So, here's my main question - will there be a noticeable difference in sound if I swap to the 8802? Or am I just upgrading to have better gear, and having separates w/ dedicated functions? I will have to wait a bit to get a high end processor, but I'm curious if this switch will imrove sound in any way...whether it be sonic signature, volume, clarity, etc.

Thanks again - I'm still  learning all this stuff! Oh, using ML Ethos as fronts, and I am mainly movies and gaming, about 15% (and climbing) for 2 channel music

@bob_reynolds i don't think its a cable issue - M & D said that it's possibly an update/patch they need to release. This has been going on for months though, so I'm shocked they haven't fixed it. Very very strange that 3 different receivers have done this...which is why I ruled out faulty motherboard/components. 

If I want to swap to the 7703 or 8802a, its a special order and will take over a month to get here...and there's no guarantee it will fix the issue. So, maybe not worth it. Plus, I don't think I'll hear a substantial enough difference in sound, so it might not be worth the hassle either.
