Axiom Home Page Forums General Discussion Advice from Axiom Owners Pioneer Elite VSX-45TX or VSX-53TX?

Hi, everybody

I'm looking for some advices from the oweners of either of these two model.

I've narrowed down my receiver choices b/w these two models. Prices are almost the same (both less than $700 USD) and specs are almost identical except that Pioneer removed RSC-232 and USB port from 53. Also, the discontinued 45TX has a nicer looking remote.

I've read the specs of these models on the Pioneer website and found that 53TX is equpped with "Dual Motorola 150 MIP / 48-Bit DSP Engine" whereas "Dual Motorola DSP Engine" with 45TX model. Are thes two identical engine? If so, Is there any advantages in choosing 53TX over 45TX?

Thank you.
