Dirac without losing resolution

I currently have a dac (topping dx9) that is fed by my pc via usb.  I mainly just use tidal.  The dac is connected into an old sony qualia 007 that I just use the built in amp.  That is connected to a pair of audiomachina UM.  I also have a rel #31 sub.

The room is far from ideal with that setup. 12x12 by 10' high ceiling.

I wanted to explore dirac for some room correction.

the issue is that I can't seem to find a way to avoid limiting the resolution to 24/192 or even lower with most dirac endpoints.

They mention that you should put the dirac endpoint (something like one of the minidsp products) between the streamer and the dac.

I was planning on getting a hifirose 130 streamer (in place of the pc).

both the rs130 and dx9 can support up to 768pcm and 512dsd.

I was trying to see if there was a way to place the dirac endpoint on the output of the dx9 dac but not sure if any of the dirac endpoints accept an analog input and then be able to process the signal for the room correction.

I am open to any dirac "endpoint" but have been directed to the SHD Studio.

It looks like that is limited to 96kHz.

Typical of miniDSP stuff.

the rel 31 sub is currently connect via the amp speaker outputs per rel's recommendation.  It looks like I could change the sub connections to connect to one of the outputs of the shd studio if I wanted to play with those settings.

Having the sub directly and independently accessible to DL is a good idea.

are there any other dirac endpoints that might get better results than the minidsp shd studio?

Why not just run DL in your PC?  I've been doing that for years and it is capable of 24/192 (in as many channels as one could wish.

Perhaps the new Auralic Aries S1 can be updated for Dirac Live soon.

I think I will take kr4's advice and load dirac suite on my pc.

I ordered the umik thingymajig and will initially test with REW.

Then I will use the dirac trial to see if helps.

thanks again for everyone's advice!

 

I also looked into using the new nova from trinnov.  I could connect that between my streamer (hifirose rs130) and either my dac or directly to an amp with xlr inputs.

I could still utilize my dx9 dac as a headphone amp as it works pretty nice with that part.  I would connect the I2S on the rs130 streamer to the I2S on the dx9 dac and listen with the headphones.

I haven't found many folks using the trinnov nova for 2.1 listening.  I think that device was designed for studio monitoring.

Although it does seem to be able to work for my use case.
