I guess it probably depends on the type of music you listen to, and what you appreciate most about music reproduction. I've not heard the DCS stuff, but the Wadia combo, particularly when tweaked to its utmost capacity, is an amazing albeit expensive proposition. Stock Wadia is fine, but fully modified and tweaked is in a whole other ballgame. It is a showpiece and is truly mesmerizing. It has tremendous resolution, communicates the emotional quality of the musical piece to an incredible degree, and I don't find it to be fatiguing at all.
