This is my latest build, a 8x8kit paired with a hi-end DAC based on Sabre32 9018.
The case is a self made 1U rack in solid aluminum with a 10mm front plate.

NICE!

I really like the idea of using external DAC´s on the minidsp - and the ESS chip is THE chip these days.

The pictures are a little to small on my screen to see the internal routing - how many inputs and outputs do you have and how is the Sabre Dac connected (2 channel??)

Did you build the DAC board yourself or is a finished diy board like Twistedpearaudio´s??

The DAC is the Yulong D18, a stereo DAC based on Sabre 9018.
The routing is CD-->miniDIGI-->DAC-->Pre

The miniDSP board manage some other input-output, 3 sub, rear sx-dx channel and cd in.

Wow... This is one of the nicest integration here.. That box and the internal wiring is very well done! Great Job Scomed99!

We'll certainly include you into the reference projects.. We've been too busy with preparing the CES show for the past month, but we'll get back at putting together that gallery of the nicest project! Sorry for the delay..

Keep it up!

Beautiful enclosure. Did you use CNC or manual machine?

What is the little PCB with the USB port?

Manual machine because it's a first class.
The little board is a miniDSP ministreamer :-)

how exactly signal route ?

I am looking to build one with external dac and look like three way stereo need 6 dac..

I saw the nonoDIGI but it is spdif but I prefer I2S ...

ANyhow if I use the nanoDIGI , is one of them can do the three way stereo?

Or the other way around , I want pure digital crossover mean one I2S input and 6 I2S output for the
above purpose then connect to 6 DAC .

THanks for providing the block diagram...

Look like it is more on home theatre plus CD integration ..and others.

Just wonder why u use the module for the purpose instead of normal home theater solution (those Dolby True HD ).

How u connect USB to the 8*8 (by I2S?) or miniDigi module as I am also looking for the connection
but for DSP crossover function to avoid ADC , still I am not quite sure how good the second part
DAC of the module.

Look like ground sound provide better convince solution on the DAC part (external DAC ship).

I am more on to use nanoDIGI to do the DSP crossover function only and use external DAC which
I am more trust to get better sound quality..

ANyhow , thanks for your responses...

DAC of 8x8 is not dab but not the best, the solution with external quality DAC is preferred IMHO.

CD-->xover with nanoDIGI-->DAC HF
-->DAC MF
-->DAC LF

Yes , that what I am looking for.

I still has one issue to get I2S connect to nonoDIGI as it will produce much better sound than Spdif.

miniDSP told me to find it myself in the module so I think it is possible but the problem is I do not know how to find it.

How did you get access to all the 8 channels of the ESS9018? Yulong boards are setup with just 2 channels right?
