Anyone famaliar with the manufacturer,and in particular this pre amp.The credentials and testimonials seem impressive.The advertised 10 day audition is appealing.
I, too, own the TD 3.0 tube DAC. It is excellent. There is a Dagogo review of it, which is located here: http://www.dagogo.com/AudioHorizonsTD3.0nDAC.html
It appears that no one with Wadia amps has tried the AH preamp out with it. Perhaps you can get one for a free home trial and let us know how it sounds.
