Lumin U2 vs Aurender N200

I have a Lumin U2 mini hooked up to a McIntosh C2700. I am using the DAC2 module. My only comparison is against a Mac Mini as Roon core/streamer that I original had connected to the C2700. The sound improvement with the Lumin was absolutely worth the money. I could not go back to using the Mac Mini to stream as I was doing before. I would not hesitate to invest in a better streamer. 

I think the next step for me would be to get a standalone DAC instead of using the DAC2 module in the C2700. I am not certain which DAC to even consider at this point. 

I purchased the MA12000 because the Sabrina X has a 2.6 ohm dip at 135Hz, but with a bit easier to drive speaker, I would expect our integrated amps to sound much the same and these guys really praised the DAC2, so leave upgrading the DAC for the future and put money into a great streamer, balanced interconnects and put some money into the right Ethernet cable and power.

Von- I agree that upgrading the Streamer will improve my sound, so many have said that it will.   Just trying to figure out which one of these two fine pieces,  hence my original questions and theme of discussion.  Thanks for you 

That Mac 8950 is sweet !!!   My Dad just picked one up.   It is a fine amp for sure. Congrats.  

I have an Aurender N200 and like it a lot.   They are actually getting ready to update the Conductor app, which is already quite good.   The N200 sounds great into my external DAC and is built li,e a tank.  Build quality is high on Aurender.  No experience with Lumin.  I tried finding a dealer to demo one near me and couldn't.    So I ended up with the N200.  No regrets

My Dad is using the Eversolo dmp A6 for the time  being.   It sounds really good but  I know it is not the sonic equal of that Aurender.    The difference between the N200 and the BS Vault 2i it replaced was not subtle.  Not cheap but some dealers will do better than list.
