I don't think I would be a good one to ask as I don't have much to compare it too, so let me run comparisons to what I have owned -
I was running NAD separates (C162/C272). Just before I sold it I bought the 7500, so I ran the 7500 with the NAD C162 preamp. I thought the 7500 took control of the room more, and is likely much better for HT (at least for me). I probably would have stayed with the 272 if I didn't want to get back into surround/HT (mainly cause I thought it was very accurate and I didn't need the other 3 channels). The NAD also provided more power than I needed (rated at 140 watts), but I really did like the sound I got from it.
The other comparison I could give you is a H/K receiver (AVR225) that I bought 6 years ago - not even worth comparing.
Oh - I am driving Paradigm Studio 60's for your reference.
From a scale of 1 to 10 - I would rate the 7500 a 9, if not a 10 (please discount this rating as you see fit due to my limited comparisons).
