If you select a Denon, last years model and this years are the same with sound quality. Only differences are set-ups, switching and possibly SS effects.
Having found my 3 year never used AVR3802 (moved several times over the past couple of years), I plugged it in place of my testing of a 3806 and there is absolutely no sound difference in stereo or HT. You can get these Denon receivers for under $500 (mine included).
But if you really want to get excellent sound from an all-iin-one, go with the B&K 507 S2. This is a bit high for the budget, but in my auditioning (including Rotel, Denon, and Arcam), I found it to be the best considerably for stereo with Arcam a close second. HT it and the Arcam were very close.
