How does the drum kit sound on your rig?

"I don't think any home system is going to really do drums. I mean the REAL THING. "

I think it can come close enough to not matter for most.

Depending on room size and other factors though, you need some combination of bigger, better and more efficient drivers in a suitable housing combined with sufficient power (not underpowered or powered to some minimal specification designed more for mass marketing appeal than for performance).

It doesn't have to sound real to sound good.
Even if the sound is compressed, it can still hit with a BANG!
If the sound can't go BANG then much is missing.
To say that drums are easy to reproduce is wrong. To me they are the essence of good playback. The color of the toms, the shimmer of the cymbals, the kick of the bass,
brushes on the snare, a choked highhat. Whew!
If the system can do these it can do a lot.

I agree...recorded drums can actually sound better than live since, unless you sit in the drummers lap, rarely does an acoustic space produce a balanced sound. I have been successful with the simplest miking for a jazz drummer by using a kick mic and a single large diaphram condenser above the kit.
