Ok, I'm posting this here because I am assuming that my input device (CD/SACD/DVD player) is my weakest link, but I'm not sure. Here is my current system Pioneer 1015TX Receiver 3 Ascend 340s up front and center 2 Ascend 170s in the rear HSU VTF3 - MK II Subwoofer Toshiba H400 DVD player/Tivo Combo HTPC using the SPDIF output to my receiver for lossless digital music collection. I bought the Ascend, HSU, and Pioneer components based on the glowing reviews that I read here and elsewhere online. To be honest, I've been slightly underwhelmed by my current system. Although I wouldn't necessarily say that I regret it either. The question Would I hear a major increase in audio performance by upgrading to a dedicated CD player (or SACD/DVD-A player) using its own DACs and analog outputs? If I understand this stuff correctly, right now I'm using my receiver for all the "DACing." Is that my biggest problem?
