Lumin U1 vs Lumin U1 mini + sbooster?

Has anyone done this comparison ? How close can the mini get ?
It will be interesting if mrcyrpuz and others who compared the U1 to the mini with sbooster, tried upgrading the DC cable on the LPS powering the mini.

I am willing to bet upgrading the DC cable will close the gap significantly between the U1 and the mini.

I have done this for my U1 mini and it is very good.

Question to everyone here using the Ui Mini with Booster (as I am).  Are you connecting to your DAC/preamp via USB or Dig coax?  

I use Black Cat Tron BNC to connect it to the DAC.

I also ground the mini via the RCA coaxial with an Entreq box.

Looking at the spec of the U1 and the mini on the Lumin site right now.

The only difference in the spec is the power supply and the higher PCM support of the U1.  


It would stand to reason that those who are saying that the added aftermarket power supply would get you damn near the performance of the U1 have a pretty solid case.  Yes, I have the U1 Mini with the Sbooster, and I'm very happy with the results when connected to my Bel Canto DAC. 

@hubbman And upgrading the DC cable for the linear power supply should close the gap significantly. I went from stock belden cables to Neotech copper and there was performance jump.
