As most everyone probably already knows, the 220V @ 50 Hz we receive over here is single phase (meaning, in the same way you have 120V @ 60 Hz in the U.S.).
At one point when living in beautiful Detroit, I did exactly what you are wondering about; I connected one of those really huge P1200 regenerators from PS Audio to a 240V dedicated circuit and (leaving the P1200 set to output 117V @ 60 Hz), got what I thought were very good results.
But, that was quite a long time ago, and right or wrong, I now have a greater level of trust in my ability to discriminate right from wrong in audio (what I want has not changed, I am just more sure of it). Also, this was back in my pre-horn days, using very nice, but nevertheless, ported-box, not-so-sensitive speakers. It would be interesting to hear that old setup in that same room today.
I still have the P1200 (if it's heavy, you can bet I'll keep it... Is there a name for this condition?); As already discussed somewhere here, I have the idea to conduct the same experiment here in Europe (symmetrical feed : 2 X 120 V via a pair of military, US-to-Euro transformers)... I have not yet done it because, as mentioned, in my current location, sound quality does not seem to fluctuate.
