I was wondering why more phono stages don't have at least a switchable subsonic filter? The vast majority of records seem to have at least some warp, which causes significant woofer movement and wasted power, at least on any speakers with true deep bass response. OK - I've heard that purists feel that it screws up the sound, but is this true? Maybe the manufacturers feel that the inclusion of such a filter will turn off the potential market for their product?
