Joe,
I don't know the W2s, but I believe that the paino timbre issue you observed isn't common to the entire Ohm line. Along with its unusual imaging capabilities, this was specifically the quality that most impressed me about my Ohm 100s. IMHO, the ability to allow a listener to easily identify piano type is usually a good indication of a speaker's timbral capability and, in this regard, I find the 100s awfully good. The "bell-like" tone of an upright is reproduced by my 100s in a way that sounds immediately real to me. With some other speakers I've heard (even some that - I'd say - sound "beautiful") this hasn't always been the case. Just MHO.
