Out of curiosity, which ST-140 do you have ? Is it the earlier 70 wpc version with the "old school" iron core transformer or the later 105 wpc version with the toroidal transformer ?
Either way, my guess is that the Superphon might sound a little more "open" and not quite as warm sounding. This is a just a guess though, so keep that in mind. Sean
