I have a FII0 ESS K9 Pro that was in that range, I understand the K17 is an upgrade. I also have the Schiit Bifrost 2/64 and pair it either with a Lyr3 or a STAX amp. The FII0 is a combo unit, very nicely built, and slightly drier but still in the same ballpark. Personally I don’t have an issue with the heat in the Schiit stack, but think you’d be OK with a FII0 K17. It checks your boxes.
Just another thought: Since the Schiit pieces both have physical toggle switches, you could easily remote the power switching to a surge protector / power strip. Cable tie it to a desk leg or maybe mount it on the underside.
That obviously doesn’t give you visual feedback on the sample rate and depth, but it’s also pretty cheap and you get to keep what you already like sound-wise.
Ended up going with the fiio k13 r2r. The k17 i was eying was no longer available. The sound of the k13 is great but it doesn’t have much power.
For the money, less than $300 on sale, it was hard to beat.
Got a pair of open box, he6se v2s on the way from hifiman. Short term I’ll drive them with my little dot mk2 tube amp but am still looking for a deal on the k17.
Look at the Topping DX9 Discrete. It’s a little over 1K new, but check HiFi Shark for used units. It’s about as good as it gets at the price point.
