Oops! The N130 supersedes the Node 2i. The U2 mini supersedes the U1 mini.
Not a Black Ice but I have the latest Audio Mirror IV, a tube DAC. I upgraded from an N130 with Sbooster LPS to a Lumin U2 mini. It’s certainly a different animal and it’s certainly a serious upgrade. Rather than repost my current thread here, please have a look.

My posts starting 3/3/23 are about the Lumin U2 mini. The optional IR remote wasn’t mentioned. It has all the functions you would expect plus an unusually fine lossless volume adjust.
