Welcome to the forum!
Outside of 3D, are there any particular features that you would like? For example, is there a specific auto calibration routine that you favor (i.e. Audyssey, MCACC, YPAO)?
Also, what's your budget for this?
I use a Pioneer Elite as my pre/pro. I only went to the Elite line in 2009 because I couldn't get all of the features (namely, pre-amp outputs) in the regular line like I could in 2005. I've been very happy with it and the MCACC auto calibration. I've read good things about the latest Audyssey MultEQ, though, and how it can also calibrate subwoofers.
