I just bought a Sony KDS-60A3000 1080p television and Sony PS3. I have mid-level 5.1 speakers (approximately $3000 for the six speakers) and DirecTV HD. I am trying to determine which features I need in a new A/V receiver. Specifically, I have been looking at the Yamaha RX-1800 ($1200) and Yamaha HTR-6090 (open item for $450, normally retails for $1000).
As far as I can tell, the only difference between the receivers is
1. The 1800 supports HDMI 1.3a and decoding of lossless formats Dolby TrueHD and DTS HD Master Audio; the 6090 only supports HDMI 1.2 (and so of course cannot decode lossless formats)
2. The 1800 supports 1080p upscaling; the 6090 supports no upscaling
3. The 1800 has 4 HDMI inputs, the 6090 only has 2.
But, the Sony PS3 does not support bitstreaming of Dolby TrueHD anyway (it internally decodes it to LPCM) and currently does not support DTS Master HD Audio at all, either bitstreaming or LPCM. And I thought that the PS3 upconverts standard DVDs, so do I really need the upconverting capability in the 1800?
My question is: Is there a reason to invest the extra $750 and get the 1800? The only reason I can think of is that the 1800 would upconvert non-hi def signals from the direcTV receiver, but I am not even sure about that.
Thanks in advance.
