Wow Phantom - That's cool that you made the move back. Funny - my wife thanked me for changing out the receiver. She likes the new receiver's 'voice' much better - the yammie had some problems with select songs with the highs, actually hurt her ears even at normal volumes - I couldn't completely tame that with the RX-A 2010. HK was actually sounding clear and detailed without any overly bright sound right out of the box - even better after manual adjustment.
I'm also enjoying the ease of use, 2 listening positions and sound choices according to input, ipod dock with on-screen controls and too many other well-thought-out design aspects to mention here. Besides the 2 channel bliss, logic 7 is great, using the 'AVR selects best mode' setting works well for most movies and TV.
I did use Dolby volume a lot on the 3600 but not much on the 7550. Not using it at all for music - even at low volumes music is superb. 3600 seemed to benefit from slight boost from Dolby volume, actually sounds better with DV set to off on the 7550.
No fan squeal here at all but one of the weird bugs with the apple tv hooked up was that the tunnel fan cranked on high randomly, and wouldn't shut off. I had to shut down and restart the receiver. Haven't had that problem after disconnecting Apple tv. The tunnel fan has come on high only when really pushing the receiver to high volumes. Just as Mcode described it auto adjusts according to temp, when I turn down the volume to a level where I can hear the fan, it slows within a few seconds to an inaudible fan speed. No cutoff when changing inputs either. I'll be curious about your experience with the unit.
I'm also really curious about that 'other something' you mention. Is it the amp, high current, DAC, or just marketing smoke and mirrors that all those nay sayers talk about when comparing SQ between amplifiers/processors? I just smile when I read that there is absolutely no difference. I can barley tear myself away when listening to music. Wasn't quite like that with the yamaha.

None are perfect and I need to realize that. However, in my room, with my speakers, and with EZSet EQII, it does sound all around better than the A3000 and way better than the Onkyo 876(especially for music). Dolby Volume, Logic 7, and ease of use are worth the money alone. Also I like that I-Pod Bridge, good looking docking station IMO.
