I've read or seen about most differences; this was first I've heard about speakers. That's a disappointment.
They have to cut down somehow..
or as a marketing strategy to hold back some features
to force the buying of the Sx900. Personally I shut off on-board speakers so I can play thru my sound system to get the sound
I want and so much better for tweaking, editing etc, if you ever play out too .., for example why doesn't Genos have speakers? ...
get my point? Also there is always the headphone option also.
But, I can see Yamaha's point targeting HOME PLAYERS with on-board speakers on MOTL units too.
