Yamaha PSR-S650 vs PSR-S775 speaker comparison

[@SaranKRS]

How much better is the playing experience and voices on the S775? Is it worth buying over the S650?

S775 feels much better than that S650 it's like they're not even on the same level. The S775's speakers are excellent and produce clean and crisp highs and boomy lows. I would recommend it over the S650. Another option is the S670 which is a slightly cut down S770. Or go for the newer SX600
