I was wondering if anyone has done a comparsion between the AMP3, Autocontruire TA2020, and DiyParadise TA2020. I have already failed at attempting to put together two Amp3 kits so I bought a Teac A-L700P amp which I am pretty happy with. I know the Sonic Impact amp can't compare to the three top amp kits I mentioned above so don't even bring that amp into the picture. I just bought a used Clari-T amp to see what the hype was all about and plan to resell it after I figure out a kit that whoops on the Clari-T amp. Well thanks for all your time guys.
