You will need to use the analog outs to your AR pre-amp I think. Your DAC has no decoder and as you stated you have no DD/DTS receiver with digital input.

HDTV/5.1 Question
Recently, I went HDTV with an off the air Samsung tuner. The tuner has a digital out jack which I hooked up to my Theta Gen Va processor. Got some strange noise. It appears that this is a 5.1 output (24/96?) and not compatible with my DAC. Is there an inexpensive way to turn this output into something I can feed to my preamp? I'm not into home theater but I'd like to run the HDTV sound through the stereo system.
