Musical Fidelity A3.2pre/power vs 308 intergrated

I was able to bring each systems home over a weekend to listen. My base comparisons are with a MF 3.2 intergrated. The 3.2 pre/power sound similar to the 3.2 intergrated only a lot better (surprise!), cleaner, clearer, more detail, better sound stage, bass etc.. but same basic sound. The A308 is more like the 3.2 intergrated in terms of detail and clarity, but with much richer mids, unlike either of the 3.2s.
Does the A308 really have choke regulation? In the MF reference guide it says it does, but not on their web-site, and in a review in Hi-Fi News they make the point of saying it does not have choke regulation. You would think if it did, it what have 'CR' on the front panel. When I bring the demos back on tues, I will ask if I could do a quick comparison between the two amps using their power conditioner and see if that makes a difference.

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.
