Yes to better sounds.
Beware of latency.
TD-20W works very well, guess DTextreme will work good as well.
If you are using alot of half-open hihats, test it first, sometimes its a nightmare to use... depending on music-style.
also, latency: I ran my computer (MBP 17, internal audiocard, MOTU midi), and got my latency down at 1,5 ms 64 samples....
You need to test the latency or you'll never get satisfied live.
Check, test, check, and teset again. .....
