How to Use an external DSD-DAC while SACD playback
I read that for some copyright reasons, SACD players have an internal DAC because they are not supposed to output DSD to an external DAC while playing SACD. (while they can use an external DAC when playing RedBook CD)

Is it always the case ?

-> Are there some SACD players that can output the DSD stream natif to an external DSD Compatible DAC ? (so that we can use our own TOL DAC instead of the internal player's DAC)

(I read somewhere that the Vitus RCD–101 can do it !?)
 
McIntosh as long as you use their interface and their DAC.
 
bmichels,

You might want to look at the combo of MSB DAC + Universal Transport. The MSB transports read data off discs and reclocks it before sending to the DAC, and since the transport is slaved to DAC, via the Ethernet cable/i2S connection. It'll effectlvely work like a computer (or server) streaming music.

That same transport will do Redbook, DVD, Blue-Ray, and SACD too.


cheers,
alex
 
The "Rules" involve copyright protection. HDMI does DSD.

My 8 year old Yamaha Reciever decodes DSD from HDMI sources.*

*No standards for DSD over HDMI from computer sources.
 
There is a company (Vanity Audio?) that will install a new circuit board in the Oppo 103 which will (supposedly) output a digital stream from any source (inc. Bluray and DSD/SACD) over coax. That's all I know about it, supposedly there is more discussion in the PS Audio forums.

thanks a lot. This board seems very interesting. It even do some reclocking !

Is there a version of the Vanity for the OPPO 105 ? Will the 105 be a better CD/SACD player than the 103 ?
 
No point in doing the 105; the 103 and 105 are supposed to be the same up to the point where the Vanity comes in.

Same in relationship to what.
The Oppo 105 has a set of dedicated stereo outputs (balanced XLR or unbalanced RCA) with a dedicated SABRE DAC chip attached to them, and then another SABRE DAC chip for the unbalanced 7.1 analog outs. The Oppo 103 does not have a dedicated stereo output nor balanced outputs, and uses the same Cirrus Logic DAC for all 7.1 analog outs.

OPPO website:

The OPPO BDP-103 and BDP-105 share the same primary components (including the mainboard, laser, and loader) for superb audio and video playback, and while the BDP-103 and BDP-105 are identical in performance when it comes to audio and video over HDMI, the BDP-105 offers a number of enhancements:
  1. The BDP-105 features improved sound quality from its analog audio outputs with its implementation of dual 32-bit ESS Technology digital-to-analog converters, a toroidal power supply, and two sets of dedicated stereo analog outputs (balanced XLR and unbalanced RCA) for 2-channel enthusiasts. Customers who do a great deal of critical music listening using a very high end, analog connected system will benefit most from these additions.
  2. The BDP-105 features a headphone amplifier for use with high-quality headphones.
  3. The BDP-105 features three additional digital audio inputs: optical, coaxial, and a 2-channel asynchronous USB DAC input.
 
Rumor states the use of a HDMI de-embeder from the oppo to external DAC will allow DSD from a SACD. http://www.amazon.com/Kanex-Pro--Em...1-1&keywords=kanex+pro+hdmi+audio+de-embedder

There no downsampling and other degrading of quality?

Does the Yamaha receiver show input format (sample rate/modulation/etc.)?

Yuri- I would not be surprised if my Yamaha transcoded to PCM, I have no idea how I would find this at the moment. I do know that the first generation Playstation 3 consoles would play SACDs and transcode to 24 bit PCM on-the-fly, however I doubt anyone could really tell. As you know, Archimago has done some good work on DSD and I support the concept that DSD to PCM at 24 bit/192Khz encodings is irrelivant to the music listener; almost no one can tell.

Back to the Yamaha, I had a yamaha DVD/SACD player of the same generation and has the HDMI output for SACDs, I think Yamaha DVD-S1800BL. When I put SACD disks in the player, the DSD logo on the Yamaha RXV1800's display panel indicated that it there was a DSD signal present.

Further, all of my DSP modes were disable, -which gives reason to believe the that Yamaha Receiver was staying true to DSD. I could do direct or PURE DIRECT and that's it.

If someone was smart enough to code a DSD over HDMI driver for Mac OS X/Windows, perhaps we'd open up a new area of audio curiosity and capability? hint hint, nudge nudge.
 
Bill, I also think if the logo present, DSD really transferred via HDMI. If player transfer transcoded to PCM HDMI code, receiver can't know (show on display) what is original.
