Anyone try the Chromecast Audio with this AVR? I have mine hooked up via 3.5mm-to-RCA analog inputs, and I'm liking it. It's also able to connect via mini-toslink, and I tried that this evening. I think I actually prefer the sound through analog. I wouldn't think the Chromecast would have a better DAC than the Marantz, but then again, it is newer. Digital in doesn't sound bad by any stretch, but it seems a bit brighter, maybe a little harsh.
I listen in stereo mode, audyssey in bypass L/R, and DEQ off. Bumping the bass up a couple dB from where Audyssey set it sounds really good.
