Contrary to the many people here, I don't like the SQ of Ares II.
I had one loan home and it sounded nasal and compressed vs my McIntosh C47.
Best input is via USB. I encountered some buggy signal dropout using coax, need to toggle the inputs to kind of "reset" the bug. SQ is ok-ish for coax.
Personal preference is OS mode, NOS mode sounded a bit rough to my ears.
Recently I bought a little toy to play and I find it beats the hell out of Ares II, SMSL D1, Gustard X26 and Topping D90. I can highly recommend it, and it is much cheaper. If you can access into taobao.com this is a good buy.

I tried to insert image but this forum doesn't allow, implementation is strange, can only insert URL where the pic is.
Anyway, this Yiniu WD6 runs on 4 x PCM1794, comes with XLR output and RCA, and you can roll opamp with it. Max out at 24/192, basic DAC with no MQA/Roon/ etc. I'm having lots of fun trying out different opamps ATM. LM49990 (single converted to dual opamp config) and OPA1656 are very good. 😄
