Rolandfan, thank you for sharing. Sounds better than the S910 but certainly does not match the quality (or the price :)) of the T4. The new speaker housing.. that`s something I would want to check out because it does influence the perception of sound quality. Yamaha have done a good job in this dept.
I got the chance to listen to a Casio WK played through a CM-110 and after a little bass boost, it was sounding like a pro board.
