I just got my 775 and have been playing the tunes on it for quite some time this evening. Got a little late so I plugged in my Sen HD590's to check out the HP capability and the output to the HP was horrible distorted. I checked the receiver's HP out and it was fine and I also checked the HP out on my Sony LD and it was fine. The 590's are not the problem. Anyone else notice this? Also noticed one thing for sure, flipped back and for between the 5.1 inputs on the receiver and the stereo inputs while listening on the HP. The processing of the receiver and the disc player are totally obvious on redbook CD's. The Denon 3801 was much warmer sounding than the 775 on analogue direct. Hopefully this changes with some burning in.
