For portable audio, I highly recommend these very lightweight (new
version maybe 8 oz) digital T-amps. Stereo, AA battery-powered or
wall wart AC. http://www.si5.com/products.php?pID=3D4046
I believe they are available at a lower price from drbott. Their
output is nominally 15W per channel but for under 200 people you
might well find that it was enough. They are so easy to carry around
compared to any other solution. I am in NY right now with four of
them in my suitcase (my demos are 8-channel).
Many of my colleagues who give demos or teach smaller seminars like
to use Edirol battery-powered self-powered speakers; ie no additional
amp package needed. They aren't that light but they are rubberized
for easy travel. I don't think they are made anymore, but here are
the AC versions, which conveniently accept analog or digital inputs.
