I have a Terminator Plus.....tried every firmware available.....i was kind of happy with the latest firmware (3.7) as it was a mix of the first firmware and the 3.6 version........ but as many others, i have some micro distortions in the tweeter and mid drivers f my ATC50....not in all songs but i think was a random problem....burn in? maybe....but i could not live with those distortions....so I flashed with 1.0 and my dac came alive again!.....
if the micro distortions are a common issue within many users why dont vinshine or denafrips check and correct this problem...i think they are doing many good things and i really appreciate that we can have the possibility of "playing" with different firmwares...but please you have to correct this kind of problems or else we will start to hate or dacs!!
