Upgrade Bluesound DAC or go to Aurrender?

Aurender A10, keep it simple! 

+1 for Node and Codex. 
I used that for 3 years.
I tried the Aurender N100 with the Codex and didn't find it a significant upgrade (though it sounded better at Audioconnection so YMMV).

I just upgraded bluesound node to an Aurender A100. Not only is it a Marked improvement in SQ but the Aurender app is light years better than blueOS. 
If you’re thinking about A10, consider A100, essentially identical units with addition of coax out and balanced connections in A10 with a considerable price difference 

Love my N10 wonderful sound.

if i understand the question right, I’d sure not spend thousands on upgrading a five hundred dollar Blue sound node.

in nearly every instance of moddifying/upgradinfg a device, the outcome regularly varies either subjectively or synergistically.

i’ve only heard upscale servers at shows, but more often than not, in numerous setups, those with aurender came off sounding more tangible and real.

then too, the dA’s in play were nothing to sneeze at either and many ranged from near 10k to well beyond 30K in a few cases.

i doubt too the particular Aurdnder in play was one of their lower end units.

i’ve not owned Aurender but have heard theior support arm is fabulos and maybe that is important to you.

IMO it comes down to how important is it given its application and the surrounding gear in play at the time?

I’ll be crossing this river soon enough as I only have the BSN 2I myself.

good luck!
