Hi Jim,
Thanks for your reply and my Logitech z5500 sounds good with psr-3000 when i play on open air stage,but when i play in church or home,the higher frequency sound gives crisp clarity but the bass is boomy and muddy ,i think it's the problem with the psr3000 output.
Have you played z5500 speakers with psr3000?and how your s900 keyboard sounds on bass side of z5500?Is there any improvement in S-900 Aux output over psr3000?
please clarify.

Thanks,
SUNNY.
