I play everything through decent studio monitors. I honestly can't argue with how much fuller, and more live the Korg's sound.

That's not to say that the Yamaha's aren't fine, should you like that compressed, CD-like sound, but if your goal is to sound like a LIVE band, there simply is no comparison.

Well... Maybe the S950's live audio drums raises the bar somewhat, but unfortunately, with only 25 of the 400 styles being audio drums, the vast majority of what you use will still be that washed out Yamaha sound. I still strongly believe that Yamaha should forget about audio styles, and simply concentrate on more live sounding drum KITS.

That would do wonders to improving the Yamaha's, IMO.
