Anyone compare LUMIN U1 mini to Sim Mind 2?

Interested in a streaming transport without a DAC. Both the U1 mini and Mind2 are in the $2k range. Just wondering if anyone actually compared the two? Aries G1 bumps it to $2900, then of course there’s a Roon Nucleus into a usb dac 
I also recently heard a new Node run into a Woo electrostatic headphone amp and a pair of Stax headphones and that sounded quite nice too

The Node experience makes me wonder if given I’m going to use the dac I already own (BRICASTI M1) is the Node really all the streamer I need? 
Your thoughts and experiences are most appreciated
