Picking a mid-tier HT receiver for optimal audio

Budget won't allow for separates for a while, but in the next few months I may upgrade my HTIB Onkyo 7.1 100w/ch receiver (which sounds surprisingly good btw).

As long as it gets the basic job done on 7.1 HT duty, I'm not too concerned about HT features (I let my TV do the HDMI switching, for instance). I'm looking to get the absolute most out of the audio quality, since this is also my primary 2-channel listening system.

The systems I've been looking at so far include:

Denon 3806
Outlaw 1070
Sherwood Newcastle R985
NAD T773

I'd love to hear some recommendations for a system that will give me great sounding audio in this range...

Thanks!

fwiw the rest of my setup:

Audionote DAC 1.1
Amphion Argon front l/r
Gallo Nucleus surrounds
