analog vs. HDMI high-res audio

I bought a Panasonic BD80 for it's high-res audio decoding and 7.1 analog outs(my Yamaha receiver is non-HDMI). I'm not really pleased with the sound I get from Dolby TrueHD and DTS-HD Master Audio over the analog outs. Dolby Digital and DTS Digital over the digital optical cable seems more dynamic. Obviously, an HDMI connection for the high res formats is the way to go. But......HDMI receivers I've researched either decode the high-res formats or the HDMI is "pass through only". A separate audio cable(digital optical for low-res audio?)is needed. So.....I need a receiver that decodes high-res audio. That's redundant. What's the point of a BD player that decodes high-res audio, especially one that doesn't have analog outs, like the Panny BD-60? Oh well....I got that off my chest.

The DACs and analog output stage in your Panasonic Blu-ray player are not as good as those in your Yamaha receiver. That's why even TrueHD and DTS-HD Master Audio sound inferior to standard Dolby Digital and DTS. I don't know how much the Panasonic costs, but it probably wasn't much considering that it includes eight channels of digital-to-analog conversion.
 
The solution is to buy an AVR with high-quality DACs and use HDMI connection.

Buying a new AVR is not the only solution. He can buy a better blu-ray player like the Sony BDP-S5000ES that plays True Dolby HD through its analog outs and has superior D/A converters to rival those in a receiver or pre/pro. It cost more than your typical blu-ray, but you are paying more for the sound. I know because I own the 5000ES and use it with my Arcam AV9 and I am completely satified.

Robert, Your 'Guide to Home Theatre' made a newbie 10yrs ago into an educated and enthusiastic audio/video philly! Thx Currently I am shopping highend cables and when I saw you visited Transparent I B-lined to this site. How fortunate so many are today to have this 'form' of fourm. Question? I am preferring Analog out on my new BDP-09 Blu-ray to HDMI but find that Dolby TrueHD tends to sound better than DTS MasterAudio for dynamic SPFX and/dialog rich Titles. Have you heard this from others running Multi Channel Analog in? Also, I am using my 3 pair of IC cables from years previous when I had a (Proceed/Bryston) pre/pro & amp. I am thinking of investing into cables but am not sure if I should be chasing ones that will transmitt or alter sound ...

 I have an 09FD also, but because i have it connected to a 2-channel, conventional system, analog out is the only option. But I noted that I preferred Stereo as my audio out choice over hi-res multichannel mixed down to 2-channels. Stereo is louder and fuller, and the soundstage is actually wider with the discs I've tried.
 
Then, with a DVD like Iron Man (which has a 5.1 surround track), I heard things that came from outside and in front of the speakers, not just from them.

Thanks for your comments about my book Home Theater for Everyone. I'm glad it was helpful.
 
In theory, DTS HD Master Audio and Dolby TrueHD should sound the same because both deliver perfectly lossless coding. That is, if you encoded the same soundtrack in TrueHD and in DTS-HD MA and then decoded them into PCM, the data would be identical.
 
I have not hear reports of one format sounding better than the other. It's difficult to judge unless you have the same program in both formats.
