TOPIC:

Hello,

Is anyone using a miniDSP product to leverage Dirac Room Correction with a GRIMM MU-1 streaming to a Mola Mola Tambaqui DAC connected via AES/EBU?  What is the signal path? i.e. where is the miniDSP product inserted?  My current signal path is; Grimm MU-1 (Roon Core and Roon End Point) --AES3--> Tambaqui DAC --XLR--> Pre-Amp.   I fear if i introduce the miniDSP between the streamer and the DAC, the magic that happens b/w the MU-1 and the Tambaqui will be negated as the mninDSP will regenerate the clock signal.  The Tambaqui will not benefit from the MU-1's reclocked output via the AES3 connection, which a key reason for the magic between the MU-1 and the Tambaqui.

Thanks,

You would be right that the quality of the AES/EBU output of the Grimm would largely become redundant. The question would be whether the benefit of being able to use Dirac Live outweighed this. The best thing for you to do would be to get an SHD Studio (if you don't need an analogue input) and test for yourself.

Thanks Ultrasonic for confirming my fear... I could also go down the convolution filters running in Roon on the Grimm route and see the outcome there,,

Hi, do you use or will add subwoofers to your system?

Note that my point was that the compromise may well be one worth making. However, if you're using Roon then making use of it for EQ would seem the logical route rather than spending lots of money on extra hardware. Although you'll still need a microphone and and understanding of what might be sensible to try.

I'm currently using a B&W DB1D Subwoofer with B&W 802D2 Speakers.

I think the improvements you will have with sub integration and dirac live (two separate advantages) will outweigh any othe loss you will have! Buy another sub will improve things further!

Yes, waits to be seen... wonder why no one seems to have tried this.. 

What are the dimensions of your room ?

Re. subwoofer integration it looks like the Tambaqui has a 26 ms latency for the 96 kHz output that the SHD uses, so ideal time alignment may not be possible depending on the delay capabilities of the subs themselves. The maximum delay that can be set on the SHD is 30 ms and you'll see some headroom for phase alignment.

Tried what specifically?

someone using a MU-1 and Tambaqui inserting a miniDSP in the middle and reporting back impressions/feedback...

I suspect you may be overestimating the likely sales of a combination as expensive as this! Plus honestly the number of people who regularly post on this forum is tiny. 

My 40+ years life as an Audiophile is divided before MiniDsp and After Minidsp. Before Minidsp I was upgrading the Digital Front End, Roon Server, Roon Endpoint,  cables etc...., with minimal to good results.
After MiniDsp I was finaly able to fix my Bass Problem. Everyone has Bass Problems. That was my BIG problem. My Room is small, 5 meters x 3 meters.
I asked for your Roon Dimentions because the smaller the Room, the better will benefit with adding Subs. It smooths out the Bass Modes.
Now I have 3 subs (with the forth on the way).
I use SHD Studio 1/2 outs to my Dac > Amp > Mains
SHD 3/4 out to  DAC2 and  goes to 2x4Hd (Analog, but could be digital too, but problaby wont matter) (I do this because SHD alone has 2 subs out only, and I have 3 subs).
First I make the Subs Integration in the 2x4hd, and After I do Dirac Live to everything.
If I had to Buy now, i would have bought the SHD Studio + Flex 8 for future proof and Convenience.

Video view of the setup...   somewhat dated, before some upgrades took place..
