Has anyone compared Lumin the U1 Mini to the U2 Mini?

I have a U1 Mini and it’s an excellent streamer. I went from AURALiC Aries G1 to Lumin and preferred the sound of Lumin.
 

In looking at new features in U2 Mini it’s mostly about processing and upsampling and new finish for the case. I never cared for the internal upsampling (capable of upsampling to DSD) to be honest so if you’re not planning on using this feature I’m not sure you’re going to hear any difference in sound. But only testing the two side by side is the only sure way to know. 

Thanks @audphile1 

That’s the information I was looking for. I doubt I’ll be upsampling anything.

Jason have you done any comparisons of servers and if so please give examples.

I think even I could answer that question…..

Not to high jack,  but does anyone know if Lumin devices can access my Vault 2i  music library through the network?  I am trying to narrow down my next streamer .
