Yamaha DTXpress/DTXplorer/DTXtreme

I just started reading the messages from this group  and had to join.
I've had my dtxpressII for about 9 mos and am starting to regain my
skills of long ago.  I used to play in a H.S. band in the 70's and
haven't touched a drum set since.  Now I can play in my own private
(virtual) world, even in my apartment, ( I insisted on a ground floor
so I wouldn't have neighborly issues) and I love it.
I hear a lot of crabbin about the cymbal sounds and I don't
understand... they sound fine in my headfones.  Is it hard to make
them sound good thru a sound system?
