ACCUSTIC ARTS VALUE

Im wondering who has heard the accustic arts reference tube preamp and their Top Series? Revamping entire starter system and Liquidating. The specs sound good but little news and reviews, sans 6Moons. Looks like they are adding to their lineup and Im wanting THE STREAMER ES as a DAC to play my HD files.
Ive got to sell immaculate 300 hrs magnepan 1.6, Rotel preamp and power amp, both 8 months old. NAD DAC integrated Amplifierbrand new in box.Ill be busy posting tomorrow! Hope to have enough to add to my savings to audition the Tube preamp and streamer.
