How to get DSD working in a networked (Roon) setup?


I recently received a few DSD albums and would love to play these.

In the manual of the T+A MP 3100 HV, I read
"The MP 3100 HV can be used as a high-quality D/A converter for other devices such as computers, streamer, digital  radios etc. which are fitted with poor-quality converters or no converter at all. The MP 3100 HV features two optical and two electrical S/P-DIF digital inputs on the back panel to allow this usage.

A USB-DAC input on the back panel permits to use the MP 3100 HV as D/A
converter for computers.

At the USB DAC IN input the MP 3100 HV accepts digital PCM-encoded stereo
signals with sampling rates of 44.1 to 384 kHz (32-bit) and DSD data with
sampling rates of DSD64, DSD128, DSD256* and DSD512*."

To use the T+A MP 3100 HV to play DSD files, I have to connect it to a PC using a USB cable? Is my understanding correct?

I have all my music on a NAS in the basement. I use Roon to play (flac) files on my stereo. Is there no other way to get DSD to play?

Ideally, I would prefer to add a device in my network to play DSD. 

This "USB DAC" truly puzzles me. 

Thank you for your advice.


Roon supports playing of DSD files.

If your DSD material is in the form of downloads, and those downloads are stored on the NAS that you currently use with Roon, then they should be available in your Roon library.  Just select the album, and the format should should show something like DSF DSD64 or some such.

On the other hand, if your DSD material is in the form of SACD disks, then it is a different story.  


I ripped all of my SACDs and stored as .dsf files on my hard drive and they are recognized and play via Roon as DSD.  Works like a charm.

the thread below (and buying a cheap pioneer player)  is was got the ball rolling for me several years ago.

best of luck 


Thank you for your reactions

@lordmelton : a DSD album on a usb stick, not SACD

The MP doesn't see DSD (*.dsf) files, so I can't plug in and play. That's exactly the issue.

@jazzman7 : They are on my NAS, but Roon transforms it into PCM and downsamples it. No purpose in DSD128 or DSD256 files if they're downsampled.

@bhoage : When you follow the signal path, is Roon downsampling? I have the *.dsf files, but it's brought to my speakers as PCM and downsampled. Thanks for sharing that link!


Very often DSD files are played using DOP (DSD over PCM).

Might it be possible for you to provide a screen print of the Roon signal path for your DSD file. 

Out of curiosity I viewed the MP 3100 HV specifications and user manual.  I now realize that it's a combination CD/SACD disc player and DAC, but that only the USB input is DSD capable.  I also viewed your very impressive rig.  So it seems that what you really need is a DSD capable Roon ready (or at least Roon tested) USB network bridge, and that for the moment you are utilizing a PC in that role.

Have you tried the front and back USB sockets with files in WAV or FLAC?

If they don't work format a USB drive in FAT not exFAT or NTFS. Also there maybe a restriction on the size of USB drive, so use a small one.

If you can play files in FLAC and WAV try a DSD 64 file and see if that works.

Your machine should definitely play native DSD.
