DVD-A and SACD thru optical/coaxial

I have done a bit of research on the topic, as I may buy a SACD DVD-A player.

From what I have read you can not pass either SACD or DVD-A through your regular optical/coaxial connection.
Q1) Is this true?

Q2) If not, why not? Is it digital protection or lack of bandwidth of the toslink connection?

Q3) The Denon 3805 audioholics review states that this receiver can decode DVD-A and SACD. How can it "decode" if it is connected through an analog connection?

I would love a knowledgeable answer. :)

By the way I am not interested in buying these type of equipment if only analogue connections are available.

A1) yes

A2) basically copyright protection

A3) from what I understand, Denon's own connection (Denon-Link) has been approved for this usage.

sure, having to use analog connections isn't as easy as a Toslink, but a good universal player will still have excellent sound quality.

The DVD Audio and SACD signals can also be passed using firewire IEEE1394 on DVD players that support this, Denon 3910, for example, and receivers that accept this---usually expensive. The Yamaha RX-Z9 does, and this combination accepts all audio formats via firewire except analog, of course.

Thank You Outsider and Dr. Audio.

I would still would like to know a definitive answer to question 2 can toslink handle the bandwitdth of DVD-A and SACD.

I think the industry is completely screwing up with these new formats. Gene della Sala in http://www.audioholics.com/techtips/specsformats/DVD-AudioSACD12.php does't see much hope for these formats because because 1) the audio improvement is not much perceptible, 2) no bass management, and 3)no digital output.

I agree very strongly with 3. What is the use of an audio format that can hold a frequency range of 1Hz to 30 Mhz with sample rates of 100 Mhz (I am of course exagerating) if it is going to pass through an analogue connection. It's like buying A CD to "enjoy" it as a 96kbps MP3. No good.

Then the industry offers a digital connection, firewire but you have to buy a $3000 receiver and a $2000 player. Let me say JA! I laugh out loud, it is not a problem of having the money. How can you seriously want to promote a format if you are selling it only to rich and voluble customers. Consider that for less than $100 you can buy a DVD player that decodes any audio and video format known to mankind.

Here the industry is at fault. A firewire connection on DVD players would add up maybe $5 at production. The fact that it is not being included is not that the technology is expensive, but there has not been a serious intention of promoting these new formats.

To answer question 1, you can pass dvd-a using optical but not sacd.
Regarding question 2, optical doesn't pass sacd because it is copyrighted by sony. Number 3, yes the 3805 will decode dvd-a and sacd by utilizing the optical for dvd-a and the multi-channel analog inputs for dvd-a or sacd. Most Denon receivers comes with multichannel analog in to bypass the problem with sacd. Also recently sony approved Denon Link to pass sacd signal.

Thank you happy for your help; however I believe you are wrong, according to what I have read.
Apparently again due to coy-protecting scheme, DVD-A (DVD-Audio) which allows audio @ Stereo, 24 bit /192 khz, or 5.1 @ 24 bit / 96 Khz does not pass through the toslink/coaxial. However most DVD-A titles come with a copy of what is really DVD-A in the AUDIO_TS folder in the VIDEO_TS folder with less quality, but can be played in any set top DVD player with the good ole DVD standard, which is a max of LPCM 2.0 24 bit 96 khz. Although I've never seen a 96khz audio in a DVD, it's all 48 khz, either LPCM or compressed (lossy) to Dolby Digital (AC3) or DTS.

Apparently, the industry is more concerned about copy prortection then promoting the format. They create a great new standard with great potential, but it can not be unleashed because they are more concerned about copy protection than enhancing the audio experience.

If you pass DVD-A through a dig output,it wont be Hi Res. Its another format if it has one,otherwise i dont get anything until i use the analog outs. My DVD-A LA Women of course wont play on my sony player but its recorded in DTS also and plays that through the dig fine.

I think you're correct. I use the denon link to pass dvd-a and this is the first time I saw a display on the 5803 that says "96khz". So I guess if you use optical it's only 48khz.
