Viggen, I've not used my A-10 much for redbook at all. I had a redbook player at the time I bought the A-10..I did however play around with it enough to form an opinion as to which settings do bring out it's best in my system as a two channel redbook player. It has a feature called Re-master, this must be OFF or it will sound steely. It also sounds best if you use it's L/R outputs from the 5.1 analog group of outputs-set center & rear to no. These outputs will play the higher bit-rate DAD disc at full res also. It's been a couple of years but I think this is how I recall it, YMMV.
