I can further attest that using the Direct Stream direct to your amplifer.....is better then using world class preamplifers in-line. I have been testing the D'Agostino Master Preamp that I just got, with the Direct Stream. After several hours of comparison, I definitely prefer the direct route. I have tried both a VAC tube preamp and the D'Agostino preamp. In both cases there is an immediate improvement in SQ, once the preamp is bypassed. There is a definite tube-like quality when bypassing the preamps. Your milage may vary (?)........but I have made my final conclusion without a doubt. It may be system dependent......I don't know. But this has been consistent with several amps, preamps, sources, and (2) different pairs of speakers.
I also have to give kudos to the Stealth Sextet XLR Digital cable. There is a major jump in quality when this cable is used. I am using this with a Bryston BDP-2 player. It has overtaken my Baetis Music Server as best digital sound in the house. And I believe it is because of the Stealth Sextet cable. Other digital cables have fallen short of this combination.
Mike can attest it was making some pretty decent music on his visit a couple of days ago. I again want to suggest this dac is a real game changer at it's price point and beyond. I continue to be thrilled with this purchase.
