A dealer I have used several times which has been excellent is safeandsoundhq. You can get an “open box” x8500 for 2999 or an sr8012 fo 2299. Full manufacturers warranty etc.

A few takeaways for me:
7705 performs worse than some avr’s. Over $2k and you get no amps
The Denon X3500 amps are actually quite good with a SINDAD (Noise + Distgortion) of 85 besting many of the seperate amps. The internal amps of the SR8012 and Denon x8500 are likely even much better. It is also very likely that the Denon 4400/4500 DAC and amps measure better than the x3500. I think the Denon/Marantz receivers offer a great value wit the built in amps and don’t give up anything in regards to performance to the 7705/8805.
Marantz/Denon receivers are very good values in my opinion. If I were going to go seperates I would actually go with the Monoprice HTP-1. 16 channels, Dirac, very good measured performance, and has compatible with the dirac bass management. I just think Marantz is behind in the high end processors. YMMV.
I also wanted to add that the bench tests I have seen on the 7703 showed the same performance as the 7705. The 7703 works with the Audyssey app as well which was the reason for the recommendation of the 7703.
