Seperates or Receiver on a Budget

I have a question which has probably been asked to death, but since I am new here...maybe you can help or point me to an answer. I am building a HT in my basement and the room will be approx 11x23x7.5 I just purchased some Definitive 2000TL's (floor models) for a steal, and wanted them since I have the PM100's and the PF1500TL sub and love the sound of the Definitives for the money....but I am tell you this for background, not to start a thread on speakers:)

My question is, if I only have $2000-2500(MAX) budgeted for a new receiver, do I start my seperates, try a hybrid or wait until I have more funds available (if that every happens). I was thinking I could go with the Yamaha 2400 receiver and bypass the amps and get started with a Marantz MM9000 amp since I have heard good things about that amp for the $$$. OR I could just look at a receiver like the Yamaha Z1 or Denon AVR4802. What would you suggest...keep in mind if you don't already know, the def techs fronts (2000TL's) center (CLR2500) as well as my sub (PF1500TL) all have powered subs, so the amps won't be used to drive the bass.
