Copy and pasted from another thread:
Rockna wavelight is one hell of a DAC.
It’s and FGPA R2R DAC that has the clarity of a chip based design, massive soundstage, 3D Layering, and a very accurate timbre. Bass has weight, density, agility, and is very transparent to the source.
You might want to throw that on your list.
Goes up another level if you use a good power cable and aftermarket fuse.
I am using a PC with a modified Matrix H USB card, battery powered, into the Rockna USB input via Silver/Gold foil USB cable. (Roon/HQPlayer DSD 512)
Rockna has the weight and density of an R2R design, with the transparency/Clarity of a chip DAC.
You might want to give it a listen.
