Lumin U1 vs Lumin U1 mini + sbooster?

I tried replacing the fuse on the LPS powering the U1 mini and that has made quite the difference.

I will also try a Farad Super 3 LPS with it.

Has anyone tried the SR orange fuse on the linear power supply for the U1 mini?

I’m kind of in shock how much of a difference this has made.

Way more PRAT, slam, dynamics, transparency.

The orange fuse is warm in the midrange.

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.
