Help in deciding a processor preamp

Anyone that could help a newbie? I would at this point (confused) be indebted to you almost forever!! I have purchased a TH-50px20 Panasonic Plasma,(the beast that started my dilemma),a Rotel RMB-1095 5 channel amp, Sony NC555ES DAC,Polk Audio's,RT12's, main, CSi5 center,Fx13 surrounds, and Veledyne VPR 12" sub (150watt).I'm undecided on a preamp processer though I'm leaning towards a Rotel RSP-1068 solely on the basis of keeping the conponents matched. I'm not sure if that a solid base for this purchase. Anyone with a suggestion for a better unit($1500>$2000)??? Thank in advance,Skip56.
