BTW, I have to say, the full Scarlatti DAC is stunning, clarity beyond clarity, detail beyond detail in an effortless way. While i still prefer my Zanden for its sheer lyrical way with music, i was amazed by the Scarlatti and felt for the first time in about 5 years since getting the Zanden that digital technology really had moved on its ability to take a simple 16/44 signal and delivery immense dynamic range, detail, and pure signal. In these technical aspects, far beyond the Zanden.
FWIW, i have heard the Stahl-Tek Vekian and felt it was also comfortably in this uppermost echelon...howver, i have recently read that the new Stahl-Tek Opus delivers all this...and greater musical/lyrical ability than Zanden. Some say the one to beat...
