Accustic Arts - Wadia?

I should clarify, I would connect DAC via a passive resistor based volume control, reason being that I do not find active pre-amps transparent, having Wadia connected directly convinced me this is the way to go.
So I am interested to hear opinions on AA DACs in comparison to other DACs and specifically Wadia, connected in whatever way, as well as any experience with AA connected directly via some transparent passive volume control, reason being that not all DACs have analog section good enough to accommodate such connection.

I have the Accustic Arts Tube Hybrid in my system, you can read a review of it here on the GON, and recently was at a friend's house who has the Wadia dual DAC/controller head reference unit and thought his Wadia digital front was the best that Wadia has produced and was a real pleasure to listen to, however I did not believe it out performed the AA Tube Hybrid DAC sonicly. Also remember that that the Wadia cost almost $30000.00 more then the AA piece.

I have listened to the top of the line Wadia pieces in the past and never really liked them, not very musical/organic though very detailed/powerful sounding, this new Wadia is very musical and for my ear's very different then the "house" sound that Wadia used to have.

Teajay,
I have seen your review, which was one of reasons for this question, to see if others have arrived to similar conclusions.
Do you recall how your friend’s Wadia sounded new, was there a significant improvement over time, and if so, how long it took Wadia to sing?
