I have an AIYIMA A07 (TPA3255) with it's stock power supply and rolled to the OPA1656 opamps. I also have an unmodified SABAJ A10a (MA12070). I really like both amps but the AIYIMA gives me a noticeably more pleasurable listening experience. I'm still trying to determine exactly why this is?
My speakers used with both amps have been the Micca RB42's and Sony SS-CS5's, both minus a subwoofer. I just purchased an S.M.S.L AO200 (DA-9's newer cousin) featuring dual MA12070 chips and haven't had a chance to power it up yet. I'm fully expecting that more sophisticated and expensive amplifier to objectively dethrone the rolled A07. I know the AIYIMA amp is an incredible overachiever, but everything has it's limits, right?
I would really enjoy hearing from any members who also own both kinds of amps and their comparatively subjective opinions and experiences. Thanks and feel free to ask me any unscientific questions concerning this subject.
