Thanx so much for plenty of good suggestions. Actually, I would not say that B&O are really good, they just sounded better than my senn, but the point is that my current headphones are quite cheap, so that explains it all. In fact, I am sort of new to this whole layer of audiophile world, so...there is a whole way to go. Today I chanced on FC1, extreme mac that is somhow connected to Future Sonics. Is future Sound a respectable & credible organization? Sorry, I've got no idea. Would anyone recommend Xtrememac FC1? Thanks so much again. P.S. I reckon that all channel phones might be a bit dangerous for hearing, no proof though.
