Linn Akurate DSM

[dubselect]

Little update,
i get used more and more for SQ that i  get out of my D800 paired with Linn ADS  through Digital out.
So meanwhile quite happy

Why don't you want to try specialized network transport like Auralic Aries or Arurender N100, N10? I bet they will give you (much) better SQ than Linn's digital BNC output.

And I doubt Klimax DS will be a worthy purchase in your case. 
I would strongly recommend you to try it before purchasing. Klimax DS sounds amazing when connected through a preamp or straight to power amp(s).
In your case the SQ will depend a lot on the Devialet ADC quality. I doubt it is good enough to show full potential of Klimax DS.

P.S. If you want to try Klimax DS, try it with a power amp (Klimax Twin or any other comparable) and with your Devialet. It will be interesting to read about your impressions.
