Thanks for the reply, Dave. Reasons for the Pioneer choice are based on my limited understanding of the interface between hype and technology, and the integration of reviews from pros and consumers.
The Pioneer has quite a few features for the money. Sound decoders--Dolby TrueHD, Dolby Digital Plus, Dolby Digital EX, Dolby Digital 5.1, Dolby Pro-Logic II, DTS-ES, DTS-HD Master Audio, DTS-HD High Resolution, DTS-Express, DTS 96/24, DTS NEO:6--with several processing options in the software like advanced surround, dialogue enhancement, and front stage surround adjustment. It has 3 HDMI ins, which seems like the minimum to get properly connected to BR, an HD broadcast source and one game box.
Its able to output 7.1. It claims HDMI switching and 1080P upconversion.
Specs suggest it is powerful enough to run an efficient speaker setup.
A minus was no THX, which leads to the next newbie question.
How do amps with no THX deal with a THX soundtrack?
