I just installed one of these in my personal home theater. I have it running in 7.1 mode with Bi-amp front speakers. I also am using the HDBaseT connection to run to a second TV in another room via Cat6 ethernet cable to a monoprice HDBaseT to HDMI converter. It is a pretty amazing system. I would like to see Pioneer update the firmware for Multichannel DSD audio file playback support via PC. (Right now it only supports 2 channel playback in DSD format).
I bought this system because I wanted a musical/listenable 2 channel system for stereo audio content from my analog sources (Phono and Reel to Reel) that I could run in "Direct" mode to skip unwanted digital processing, as well as have an awesome home theater system for DTS/Dolby Digital 7.1 playback.
I think the Sabre32 DAC sounds wonderful and I couldn't be happier.
