Paradigm is a great match with yamaha. I would suggest the monitor 7's with the cc270 center and either the minimonitors or adp370's as surrounds. As for a sub, I would suggest an Hsu stf2, or Hsu vtf2 mk2. This 5.1 setup is great and can be had for around $2000. Go to a local dealer and listen, you won't be dissappointed.
