I have a Fosi V3 I got after returning an Aiyima 07 both used in my workshop system with restored IMF Super Compact 3-ways.
Source is WiiM Pro analog out. I also have a Van Alstine Super PAS 3 and new build Dyna ST35 for comparison. I find the Fosi to be crisp, transparent, and enjoyable. I do slightly prefer the tube gear, but when I need space on my bench, it goes in the rack and I am happy with the tiny stack. I also use a Bellari PA550 as preamp in that setup, for phono.
