anyone compare HD DD w/ DVD to 1.3a receiver in?

Basically, I guess I could setup the following scenario's, and want to know what peoples experience with the exact same setup's have yieled, in one or all of the configurations, comparing them to each other. In short, which did they think was the best, and what equip did they use to get their results. So here are the scenarios:

You have a Blue-Ray or HD DVD player that process Dolby HD+ and DTS Master lossless compressed audio in ternally, and you have an AV receiver that has a capable 1.3a HDMI input, and the receiver also is capable of processing the above audio codecs. (possibly LPCM as well??? - doubt it). This/your same AV receiver or pre/pro also has 8 channel direct inputs to compare both processing methods and connections. Have you compared all the variables here, and what have you found? Was one better than the other for either standard DD/DTS 16 bit tracks? How about the HD Dolby and DTS master lossless? How about for LPCM? How about for standsard 16 bit or HDCD decoding (if available in the pre/pro or receiver as an option)?

Also, you have possibly the above equipment, processing and equipment options, but you also have an outboard 2 or more channel standard analog preamp or integrated amp to compare as well - with which to, say, connect dirrectly from your HD or Blue player into the preamp, forgoing the AV pre or receiver all together. Then what did you find with these formats?

Input, and actual experience/findings appreciated. I wanna know who's seriously compared all of this. Cause in the end, it does matter, sonically.

Well, I'm not at my house right now, and unfortunately won't be for another month. But I can't wait to get back there and report the results. I'm not too worried about 2-channel audio, since I could still use an optical to my Squeezebox. Supposing multichannel PCM and high resolution formats, I am merely speculating right now as to what could possibly cause a difference:

1. DAC - That is a given.

2. Analog stage - In most pre/pro's or receivers, an ADC would be necessary for bass management, etc., before the final DAC to speakers. If the pre/pro allows analog passthrough, this shouldn't be a problem. I can couple that with an analog bass management/crossover system.

3. THX Processing/DSP's - In my experience there's a tradeoff of imaging for dynamics. I wouldn't mind leaving this off.

4. Room correction - I couldn't tell exactly what Audyssey was doing. It made my already bright Monitor Audio speakers brighter, and changed the soundstage a bit. Another one with tradeoff's.

5. DD/DTS Decoding - I think most experts agree, especially with the lossless formats, that it doesn't matter which component decodes this.

I can also only assume what Kal heard was inferior analog stage in his processors, based on his comments. If the Oppo/Anthem sounds better than Oppo/Integra analog, and this is using the same player DAC's and processing, then the only difference is what's after. Please note this is only my opinion and I'm not trying to imply I know more than Kal.

Enough speculating, though! I, too, would like to hear from anyone with actual experience. I've been struggling with this decision for months now and eventually settled with going the analog route, partially from a financial standpoint.

I disagree here. I've been not only doing audio/video for almost 20 years now, but have been reading all the articles, been to the tade-shows, installed 100's of systems, talked to many many audio equipment engineers and industry experts, and they have all unanimously concurred that THE WAY to connect your DVD player for the best possible DD/DTS sound/processing (not necessarily cd playback, mind you) has been connecting DIRECT DIGITAL (almost always Coax, sometimes digital XLR or ST Glass optical where aplicable..but usually always coax digital) from your DVD player's digital out to an outboard DD/DTS decoder of some sort, typically to the digital input of an AV receiver or AV pre-pro! They ALL found out too that the either the DD/DTS Dac's and/or analog output stages and/or a combo of the two were not as adequate as simply passing the DD/DTS bit-stream to a more capable outboard processor! In fact, that is why even as of late you would never ever ever ever hear any pro audio reviewer worth his salt tell you that he has his DVD player hooked up with the "analog connection" to his preamp or AV processor! - NEEEEEEEEEEVER! Why? because it's been very common knowledge that this has not been as good...we're talking limited dynamics, 2 dimensional sound-stage, weaker pressentation, etc.
Now of course I'm referring to the last 12 years or so of DVD DD/DTS application. I'm NOT referring to the new HD codecs! Still, and yet, has anything changed since then? Why would it then all of a sudden, since there's higher resolution being made available, now be better or even ACCEPTABLE to connect otherwise?!!!!!!
Does this make sense to anyone?
I mean, don't take my word for it, just read back for the last decade+ any artical from an AV receiver or pre/pro's review on how/why they use the digital connection from the DVD player to the processor. Because that is EXACTLY how they did it! Then, of course, if you read enough, you'll actually get an article saying that this is the preferred method, result-wise. Bellow are some examples:

"A digital audio connection is best; not only because it typically sounds better, but because it will allow your AVR to use 5.1-channel Dolby Digital or DTS processing." (Darryl Wilkinson;Home Theater mag, on connecting an AV receiver with DVD)

"...One thing is certain — either one(coax or toslink) is better than an analog two-channel connection" (Mark Fishmenm, on connecting DVD; Crutchfield)

"Though one exception is DVD players that contain an HDCD decoder, which can give compatible CD's a boost in audio quality. However, a digital connection should still be made for movie listening." (Techlore.com, on dvd connection)

"Based on our experience with traditional DVD players we would normally expect to get better sound from digital connections. After all, good A/V receivers normally have better DD decoders and Digital-to-Analog Converters than those inside DVD players." (Satliteguys.us, on standard dvd)

Oh and there's simply soooooo many more, that I think we all agree, that over the past decade, if any knuckle-head were to tell you that you should hook your DVD player's audio up with analog cables, for DD/DTS playback, you'd either turn and walk away or laugh at them, or both!!
Am I right here, or is this just me?...Please give me some feedback...perhaps an "Amen" here. Or am I just crazy?
Now again, things could have possibly changed since the new codecs hit the scene (particularly when Blue and HD players hit the market, and there were NO RECEIVERS OR PROCESSORS that had this technology built in for internal process). But now that you can process in an "either/or" scenario, let the truth be told about which connection is best. Capiche?

So, yes, I'd like to here some more experiences here, specifically in regards to the new HD codecs and DVD hook-up options for best sound. Thanks

Same answer as in the pre lossless codecs/blu-ray world. Connect using the HDMI to a processor that decodes lossless codecs rather than via PCM. The better processors use better components (ie. DACs) and sampling rates so a bitstream connection is best (i.e., a good quality HDMI cable)....imho.

I'm using a new Cary Cinema 11a processor.

Maybe the reviewers notes you posted were talking to the masses and not the higher end AV buyers? it makes sense to me that they were, by and large, accounting for those who have bought DVD & CD players well under the $200 marks and possibly even less. Given then their usually much more expensive AV reciever's DACs would then be readily more capable of processing digital signals.

Given even simple costs a single cable type interfgace, if good performance can be had from it, seems both the economical and wisest choice.

I have since played with various connections to the receiver via coax analog & optical, and realized such marginal differences with none being that night and day diff, I have just kept the HDMI connections to those items possessing such ins & outs. Analog elsewhere.

Due to the info at the time or point of purchase, I looked for HDMI explicitly for use as my sole AV HT interface. Primarily for costs and ease of connectivity.

Naturally the additional aspect of upsampling SD video to higher resolutions too, which I've since found out isn't the end all be all I thought perhaps it should be. But it's not bad either. Just not a significant enough aspect for a buying decision to be made upon, for there is darned little difference in image sharpness or color vividness by their said escalation. Also too the higher res audio carried on 1.3a is attractive too. This last feature might well be improved upon using analog cabling for audio at least.

In each case though I want to point out the 'bottleneck' as it were remains the processor (AV receiver or player), and it's doubtful to me the use of analog cabling will severely increase performance with todays HD capable devices.

it will however, severely increase costs. Eight times or even six times more just for audio.

I'm not motivated to alter the interfaces to other digital ones, for audio, nor to analog for video. What I'm getting via HDMI now is definitely good enough in both instances for the theater experience to be most involving. IHMO

My sole use of analog cables is for connections to outboard amps, sub, and speakers. I am going to add one RCA composite video from a VHS tape deck to the AV reciever only, as the rec allows such video to be passed along onto the HDMI output cable and then out to the projector.

It may well be otherwise for some, but I feel the mention previously of current digital processing is greatly improved
over past efforts. so much so I'm pretty comfortable with sticking to the one cable 'HDMI' fix.
