DSD export is independent of the DAC. Its all host based processing. However the code is heavily optimized for SSE2. If its crashing on an export in even a project with a single wave file then its most likely some SSE2 incompatibility.
Phenom's definitely support SSE2 so I'm not sure why this would fail - perhaps a microcode bug or something. I doubt this was tested on a Phenom so I'll pass on the info to TASCAM in case its something they can fix.
 
If you have another machine you can test it on you can try an export there...

There is a laptop with Windows 8 and I have a Focusrite 2i4 for the ASIO side of things. Although it's a mere dual-core Pentium B processor which might have issues with the power required for Sonar.
 
Beside that, that would really upset my workflow transferring between systems.  Admittedly I never bought Sonar on the premise of encoding DSD files. However with my recent introduction to DSD and PDM it got my curiosity. I always just thought it was something rich people used in their chauffeur-driven cars. Although I do have a couple Hybrid-SACD albums.
 
Thanks for the support and before someone corrects me, it is PDM (Pulse-density Modulation) which is not the same as PCM (Pulse Code Modulation).
 
I know because I seen that in a cracker.
 
One last edit:
 
I ran the same process on my laptop and it worked without any perceivable problems. So essentially when I want to want to offer an alternative method of download or archive things in a higher fidelity, I may be using this as a way to do it. 
 
I'm using a portable FiiO player to play this stuff back and play it natively, so it's not a complete exercise in futility. Sorry for hi-jacking the thread. Anyway back to the original topic.
 
 

Thanks for this info. The instruction that is failing is an SSE3 instruction which your CPU should technically support.
I'll ask TASCAM if there is a potential workaround - perhaps they can use a different instruction that is more compatible on Phenom. 

 

Hi all!

Great info in this thread! 

I don't know why they're not mentioned but, Roland recently released a couple of brilliant DSD-capable interfaces:

FWIW, I've never heard anything sounding better than DSD-files through the UA-S10. I was really sceptical but not anymore :-) This is the future.

Best Regards

Once I find a source of DSD of music I am happy with, I'll report back. Although I have played back one on my FiiO X3 ii player which is DSD compatible and the results are really good. I listened with AKG K702 headphones and Shure SE425 In-ear Monitors. Although I haven't tried through a Line Out source  as yet.
