all you need is a receiver with HDMI input that can handle multi-ch PCM. Almost all of them can. The only ones that I can't are bottom of the barrel, and are "video pass thru only". Voila.
If you are going to have anything more than 5.1 setup, then you will have to research if any given receiver can "matrix" multi ch PCM. Most of them can. However, for example, the Onkyo 605 cannot.
I think some benefits of the new codecs include better definition and increased dynamic range. HOWEVER, I would consider the following all to be more important:
-choice of speakers
-careful speaker placement
-choice of sub
-sub placement
-room acoustics
-adequate amplification
Once you have all that more or less considered, then would I find lossless audio to be icing on the cake. If your amp/receiver can't handle complex loads, then what's the point of getting greater dynamic range anyways?
do I need a receiver that can, or just a receiver with hdmi? Currently I just have an older receiver using an optical cable from the ps3 to the receiver with the ps3 set to bitstream, but from what I have been reading is the ps3 can not send dts hd and dolby true hd through bitstream, only through pcm using hdmi.
So if the playstation 3 is going to be used as the blu ray player and the audio output is going to be set to pcm, and the ps3 will be connected to the receiver using hdmi, what kind/type of receiver do I need, or what features does this receiver need?
Thanks and any help is appreciated.
