Lumin U1 vs Lumin U1 mini + sbooster?

I own a Lumin T2 and do not feel a need for an outboard dac. Using the T2 with an outboard dac defeats the design purpose.  I went from a MacMini to the Lumin....the change was stunning and obvious to me, something I liked. However, everyone's ears and gear is different. YMMV.

@tvad  impressive. I wonder if you would get a further gain with a better PSU on the mac mini ?

I agree 100% with Grant here @tvad ..... one can be very happy with a MacMini setup, like he is, and like I am too...

I run a late 2012 MacMini (2.3GHz I7 quad processor) with 16Gb ram, a Samsung 860 Pro solid state drive, with an Akiko USB stick on one of the USB ports.  I am using USB out to a Gustard U16 DDC that gives me an AES/EBU output for my DAC.

I have an HDPlex 200W linear power supply which I will use to power my MacMini when the MMK power kit arrives sometime in April, from Uptone Auido.

The point is, like Grant, I listened to an audiophile streamer (an Innuos Zen mk3) in my system, directly compared to the MacMini setup, and while I may be in the minority here, I really preferred the MacMini.  This is with the stock power supply.
