Lumin U1 vs U1 mini + sbooster?

[Terry A Khan]

Owned both units.

I will start with Mini first:

Tried Mini with S Booster, HDPlex and Teddy Pardo power supplies. 

Mini sound best with Teddy Pardo followed by HDPlex 200.

Next:

U1 with it's stock external power supply is light years ahead of the Mini.

This how I find it in my system, sold off the Mini, trying to sell off U1 upgrading to X1.

Hello,

I am not using the U1's USB, I am only using the AES/EBU output.

Yes, i think, you are correct, the route you have suggested is a real bang for the buck, yes, X1 PSU and cable is on my list now.

Thank you

Only the Lumin Mini with Teddy Pardo 12vdc/4.5 amps.

The Mini offered a kind of sweetness out of my planars, I simply just wanted more, the U1 has really satisfied my appetite. 

Next step is to do the Lumin XI which carries it's internal DAC against my PS Audio DSD dac without the Bridge II.

What would be nice if there was a Lumin standalone DAC like the U1.

Sorry for digging up an old thread but when replacing the stock PSU in the u1 mini are we connecting a ground wire or leaving it disconnected/ungrounded?

 

The stock smps unit grounds through the cage of the switching power supply so without a dedicated ground wire you're running without.

Yes, you will have to leave the ground wire disconnected, I simply tape down mine on the frame. 

However, the Lumin offers an external grounding nut, I suggest to use it.

Only cut the red wire in the middle of the length, this will allow working room if you made need to return to it's original state eg for resale.
