So no floor standing speakers? I like the looks of them.
I'm running SVS floorstanding speakers (I like the looks too) and dual SVS 10" subs/ported which sits side by side to the tower's due to a small room size.
After running Audyssey on my Marantz SR7010 to calibrate room acoustics it set the floorstanding's crossover to 40Hz (selfish to the subs). I use to bump it up to 100Hz to drive the subs more and floorstanding less (like others mentioned a waste) but for some reason the last time I ran Audyssey it sounds great at 40Hz and the mids and highs are crystal clear, maybe a break-in thing I only had the complete system for 3 months. The sound of the subs blend in very nice without over or underwhelming the floorstanding speakers in a small family room 12' x 14' gives a fuller sound but I believe it's due to Audyssey's work. I'm guessing it would sound even better in a larger room moving the subs to the far left and right sides away from the floorstanding speakers but may require larger subs depending on room size.
One thing I like about the Marantz SR7010 are the separate discrete sub outputs and Audyssey SubEQ HT that comes with it. When EQ'ing the room, Audyssey SubEQ runs first to sync the subs by adjusting delay and levels for each sub separately. If your sub gain is too high it will display a dB gauge on the TV screen and let you adjust each sub to 75dB level, then Audyssey continues on its normal calibration. My subs gain ended up at 10 o'clock with decent sub trim levels in Audyssey settings.
Some good recommendations mentioned in this thread, you can't go wrong with Marantz if you're looking for sound quality for music. I mostly listen to music and at higher volume levels and the Marantz doesn't give in and sound has much clarity and clear separation. I never enjoyed listening to music as much as I do now, my previous mid-range Onkyo with the same speaker/sub setup was rubbish compared to this.
Spending that kind of money I would consider the higher Marantz models as the SR6010 and SR7010 even worth going over budget. Besides stronger amplification they also come with a phono preamp if you decide to connect a turntable and spin some vinyl, although you can always add an external preamp but this is Marantz's version of preamp, I know you mentioned more for music listening, enjoy!
