I ordered a Fi Y, but have not received it. I can tell you more in couple of weeks. Art Dudley was(is?) using the original Fi preamp. Maybe worth dropping him an email.
I have the copy of Art's reveiw of the Fi pre, but would like some more feedback from nonreveiwer types. Not that I do not respect Art's opinion, but He is the only one that has ever really said anything about the Fi pre.
I have spoken to Don Garber and he is still in prototype stage but hopes to finish soon, too busy building amps.
PS anyone have Art's email?
