Re: Opinions on the Sony DG820
Turning it up to get decent volume is not a bad thing; it merely shows that the engineers who mixed the track wanted to use the full dynamic range of lossless audio without distortion.
Question: I was looking @ the 720 the other day. Do all three HDMI ins output LPCM or are the DVD and cable ports merely pass-thrus?

PCM 48. FWIW, I have the sound processing set to Neo:6
Now I have my HD DirecTv into the Video 2 HDMI port. When watching any HD program on it, it will show 3.2-1 or something like that.

Thanks. That's what I needed to know.

PCM=Pulse Code Modulation. I believe 48 is the sampling rate of a dvd. A cd is 44.

I didn't want to saw anything, but that was a smart move. Not that Sony receivers are all that bad, but there are better alternatives.

Re: Opinions on the Sony DG820
A sampling rate can be 44.1(k), 48(k), 96(k), and 192(k). CD's top out at 44.1k, dvd's at 48k and DVD-Audio can be 48k or 96k or 192k. Then there's the bit rate or word lenght. Cd's or 16 bit, 44.1k, dvd's 24 bit, 48k, and DVD-A 24 bit, 48-96-192k. You're really testing my memory. I used to know this stuff but something tells me I'm screwing it up!

I think you've got it right. Sampling rates are measured in thousands of cycles per second, so 44.1 kHz and so forth. The argument for 24 bit is that it makes the sound more open and closer to source, as each "word" in the bitstream is larger and can contain more detail. Some formats employ a higher sample rate to reduce error in D/A conversion when the sound is played back (like DTS 24/96); however, some pieces of hardware have D/A converters with higher-than-recorded sampling rates to assist in error correction (oversampling), so trying to reach the same result but by different means.
All that being said, I think I may consider pairing the 720 with a Panny DMP BD35, since it decodes all the advanced codecs internally and is profile 2.0.
