let’s keep the list to the brands that are worth buying, none of the cheap stuff that’s suspect.
lots of known names, but perhaps we’ll learn about others we weren’t aware of!
edit - you can include hybrids and combo’s with a DAC as well.
edit 2 - guess I will throw in a couple I know:
Little Dot, which I believe you have to buy off of Ebay
Schiit has a couple too, the Vali and the Valhalla.
