Wel, I am going to try and answer my own question. The MF 3.2 pre/power that I listened to had several hundred hours on it whereas the A308 had less then 100 hours. The biggest difference was that the 3.2 combo was very clean, clear and detailed,especially in the highs, but kind of thin sounding. The A308 had a fuller sound, especially in the mids but lacked the clarity and detail of the 3.2 combo. I am a bit surprised by the results. Reviews on the A308 rave about the clean clear highs but I didn't hear this. Could it be that the A308 needs more hours before the sound starts to open up? Alternatively, I am in a older building with not the best wiring and the area where I live suffers from irregular power. Are the differences that I am hearing due to the choke regulators on the 3.2 and could this be improved with a power conditioner? I would really like to get the fullness of the A308 together with the clarity/detail of the 3.2 combo.
