Thread: PCM & DSD

Will try and keep this simple.

I have a PIONEER DV-565A DVD/SACD and a YAMAHA RX-V76 RECEIVER.

Playing a DVD the receiver will recognise all formats ie DTS / Dolby Digital etc.

Playing SACD or CD all my receiver displays is PCM.

I can find no way of putting an SACD in the Pioneer and my receiver displaying DSD. The Pioneer manual is actually excessively vague when it comes to SACD.

So my question is what can I do to display DSD or is my Pioneer simply not capable

Keep it simple please lol.

Many thanks all as ever.

Doug.

Your player has no HDMI socket/output. DSD cannot be transported by SPDIF coax or optical, the sample rate is too high. HDMI is the most common transport for consumer devices.

You will be only getting downsampled stereo PCM across the SPDIF interface, and as you say this is unspecified in the manual. An inexpensive Sony universal player will allow you to transport DSD.

But as others have pointed out here you may be better off with utilising the Yamaha Parametric Room Acoustic Optimizer in conjunction with PCM.

BRILLIANT that's what I wanted to know - thank you so much. All understood.

When It comes to SONY, I would not use the term "universal" player! they do not support DVD-A like OPPO. However some of SONY players have stunning DSD output through analougue connection comparable to newest machines from other producers.

Furthemore Pioneer players from "5x5" production line has no option to decode real DSD, even if they were HDMI capable transfer to my knowledge. They all converting DSD stream to PCM (all of them).

It's not DSD coming out of the analog connections -- it's the DSD signal converted to analog.

DSD cannot be transmitted across non-encrypted channels as far as I know. Hence although the bandwidth of SPDIF might not be stable enough to handle DSD it is also not a secure channel. I don't think your player has any secure digital output options.

Not too sure how you have your player connected to your receiver or how configurable your player is but I would suggest that using the 6 RCA analogue channel connections into your receiver for your SACDs is a much better option. Basically the fewer steps/interventions from the source to the output the better. DVDA can use SPDIF or Optical as this is PCM but this might also be limited by the configuration options for SACD/DVDA multichannel discs on your player.

I'm not too sure if your receiver support DSD over HDMI either. Can't see anything in the online spec.

I'm guessing that you have the RX-V765 (I think you forgot to type the "5").

If that's the case, your receiver will accept a DSD signal over HDMI, but I'm pretty sure convert it to PCM.

As pacwin notes, that's kind of moot because if you apply any kind of room optimization or bass management the signal is getting converted to PCM anyway.

I'd say buy a $100 Sony Blu-ray player like the S590 that will output DSD over HDMI (so the Blu-ray player will do nothing to alter the DSD signal). You'll also be able to bitstream DTS HD tracks on Blu-ray discs.

It can, but only if the DSD source is unencrypted. With home-made DSD recordings or DRM-free DSD downloads you can transport the DSD over USB (disguised in PCM frames; it's referred to as DoP for DSD ver PCM). With SACD the only options are i.Link/FireWire/IEEE1394 with DTCP and HDMI with HDCP. See the /faq#playback9

That's right.

Correct too, I reckon.

Hello.
Are the SACD-R unencrypted?
