Here is a simple system that would probably blow most people away:

Resolution Audio Opus 21 (3500)
ATC Active 20's(6K???)
DNM Interconnects (400?)

If you want a full range system you could look at a ATC sub, but that would take the price over 10K.

Another interesting system might be:

Resolution Audio CD Player (3500)
Resolution Audio Amp (3K???)
Tannoy SYS1200 (3500?) or Rethm 4ths (2750)
DNM Interconnects and speaker cable (400)

Anyway, that is what I could think of right off hand...

Now if you say used is ok, we have a whole new ball game...
