I have both a recently John Wright upgraded Bidat and Bitstream DAC and I enjoy very much. The Bidat is in my higher end living room system while my Bitstream is in my bedroom system. They are both very musical and resolving. I have had them on for about a month or so and the initial limited harshness is gone. Quality DACs really do make a significant positive difference to the music!
Museatex Bitstream vs Bidat
I've emailed John Wright asking exactly how big a jump in performance there was between the Bitstream and Bidat. He mentioned that when both fully modded they sound different from each other and neither was better then the other. The bitstream being more musical overall, while the Bidat picked up more inner detail. Anybody compared for themselves?
