Although this is silly, as both units are pretty much identical, performance wise, but I prefer the way the Onkyo Pro 885 looks.
I was going to go with the NAD T175and Axiom A1400, but NAD screwed the pooch as far as I'm concerned. They delayed production so that they could use the HDMI 1.3 hardware, but then they announced that the unit will not process anything other than Multi Channel PCM and the unit will not come with DTS:HD and DD-TruHD decoders. I do prefer that NAD has left the video processor out of the mix, but no advance audio decoding is ridiculous.
Now I'm just waiting and enjoying what I have, and plan to rob CV.
