Yamaha DTXpress/DTXplorer/DTXtreme

Most all the information I've been able to find on the net relating 
to the DTXPRESS 2 'live' capabilities (i.e. through an amplifier) has 
been very limited. In fact I've only ever seen reference to use of 
headphones. I expect to get a DTXPRESS before long and wondered what 
other members put their DTXPRESS through at home when they want 
it 'live', and also what their opinions are. I note that the local 
Yamaha dealer does not have his display kit set up through an 
amp....headphones only! To me, this is a ploy to ensure any potential 
customer only hears the best sound possible?
