If it is going to be converted back to PCM for playback, I guess I don't see much advantage.

The a/d in the v3 does 1 bit conversion and can output dsd or pcm.  Essentialy, every v3 a/d is always converting a 1 bit stream to pcm.  The v3 does it in hardware, audiogate in software.

Also wondering what it will cost to convert dsd to pcm in 10 or 20 years.

There is always the chance that dsd will take off.... but pcm is very entrenched and very good. If the movie industry wanted dsd to go with their HD/imax/etc, we'd see more products.  SD would just release a new a/d board for the 7xx.

listening to a couple of discs recently that were mastered on DSD but released as redbook I am hooked on the sound. It is alive and 3d in a way that PCM is not. It's not analog but it's got more texture than PCM. I really dig the sound.

what I have heard from the Korg boxes is very good. IMO though it's hard to really judge gear for our purposes unless you have it in your hands and were in the room when the tape was made. Preferably with a set of mics and a pre that you know well in a venue that you frequent. That caveat aside I like the Korg boxes.

I hadn't thought about DSD to PCM conversion in the future, that's an interesting angle...

But the nice thing about DSD is there's no disadvantage to converting to PCM. If I configure the audio on my PC to run at 96/24 it gets converted to pretty nice PCM.

I don't think the long term archivability of DSD is much more of an issue than it was for my open reel. The format was designed for archiving. Plus my PC will still run most software written 20 years ago.

10 / 20 years from now dsd will be like mp3 compared to its master rival.

"1bit"...,

now, i'm stretching the limits of my conversational knowledge of things a bit...., but as I understand it all (or almost all) DACs do 1 bit conversion in the Delta-Sigma stage of the signal conversion.
it was the idea of all that "junk" after this wasn't needed, and you could just capture that direct stream from the first stage of conversion.

and..viola.
dsd is born.

but, its a tad over my head.  I read something on it once that really made sense, and I think its somewhere in the bowels of this 24pg thread.
here is some info: http://en.wikipedia.org/wiki/Delta-sigma_modulation

You can download and install Sony's DSD->PCM codec onto any Windows system to playback MR-1 DFF and DSD files in WMP. It doesn't support WSD format though.

Anyone have a link for this?

Just wondering why Sony hasn't put their foot on it yet...all their new laptops can convert PCM to DSD and play DSD files (can't remember what format) using WMP (?)

You can download and install Sony's DSD->PCM codec onto any Windows system to playback MR-1 DFF and DSD files in WMP. It doesn't support WSD format though.

I think WMP plays 1-bit files with '.dsf' extensions.... Also I thought the conversion was PCM to DSD in their sonic program.

My WMP will not play my files with .dff extensions.

Anyone run a SBD patch to the MR-1? I wonder how the input would handle that kind of a hot signal...

Technology for technology's sake means nothing in the market. As vast numbers of failed startups demonstrate.

1bit format DA conversion is super simple compared to decoding PCM. Theoretically, it should also have less artifacts.

Either one can be trivial because you are simply using one of the many off the shelf chipsets.  The non-trivial aspect is a great power supply and great timing.

And less noise in the 1bit case.
