Thanks for these responses guys. Just a little more insight, to my ears the MH1C's mids are too recessed, and the top-end is lacking a bit. What I don't want his to go completely in the opposite direction and end up with a sibilant top-end. Bass quantity with the MH1Cs is OK, could do with being a little quicker.
@ljokerl, if you see this how would you compare these the MA750 and EPH-100 in terms of sound signature? I've read several of your comments as well as others on various sites and am now rather confused. Some have said that the MA750 has more recessed mids, less bass, is brighter sounding than the EPH-100. I know you don't like making comparisons of equipment when you don't have them on hand, however how would you compare them to each other, as well as the MH1C (mainly in terms of signature here)? Many thanks :)
