I am considering the new Panasonic F85 5-disc DVD changer, specifically for its DVD-Audio abilities. As this will be used >90% for DVD-Audio as opposed to DVD-video, the quality of the Audio is important to me. I understand that this unit uses a Burr-Brown PCM1604(k) DAC, which is a good DAC, though not their best (but the k-rated parts are the pick of the litter so to speak). I also understand that this unit has Panasonic's "Double Re-Master Processing" which is their way of saying upsampling. This apparently works for CD, DVD, and MP3, but I don't know whether it is active for DVD-Audio (i.e. at 96 kHz or lower original sampling rate of course). I'd like to hear opinions on sound quality for both DVD-A and CD, as well as comments on build quality and user experience (easy or cumbersome operation, etc.). Thanks in advance.
