Looking for speakers.

I was recently lucky and blessed enough to get my hands on a Harman/Kardan AVR 25 Mark II.

I am now looking for speakers to do this unit justice....

I have looked at the B&W 603(s) which seem to be very high quality...

Any better recommendations...

(edit) -- I would only be getting two speakers atm, then when the budget allows a center, and eventually two rears..

Thanks...
