In an effort to consolidate my system, I am thinking of getting an Emotiva PT-100 to replace my Emotiva XDA-2, my VanAlstine-mod'd Dynaco PAT5, and a tuner. I seek opinions about the SQ of this move. I don't really care much about the tuner quality, so forget that. I imagine the DAC in the PT-100 is pretty similar to the XDA-2 (or is it ?). However, the AVA PAT-5 is pretty high-regarded I believe, and has always sounded great to me; so that's probably my main concern, the sonics of the PT-100's pre-amp section versus the PAT5. TIA !
