Dermott, since nobody who actually does this has replied, I'll give you my view. If you mean can those SACD and DVD-A tracks be played through an integrated stereo amp, the answer is that sure they can; the left and right front analog outputs would be connected to the CD inputs on the amp as usual(the player would select what tracks are being played) and the sub out would be connected with a coaxial cable to a powered sub. Whether there would be any noticeable "advantage" would be another matter. The main attraction of these formats is the possibility of multi-channel surround music play. Re-mixing and re-mastering for these formats may or may not result in better sound than on an old CD of the same performance. Stereo playback may or may not be noticeably better.
