I don't know if it's me or if it's real but i find the quality of the Korg m3 sounds superior to the one i had on my s910
Your talking about two completely different technologies, so it's no wonder. It's like very old VS very new.
The M3 is based on the almighty OASYS, and it's EDS sound engine is new and ultra deep. Its an evolution of AI1, AI2, Access, and Hi-Sys. So your talking about 5 different synth engines of evolution in total.
Where on the other hand you have a Yamaha S910 which uses AWM2. Yamaha have been milking that cow for 15 years or more and have not developed a new PCM based engine since.
My 2 cents.
