Sorry, I meant the KA1 or KA3, got them mixed up. My KA3 was like $50 used.

I use it on my PC, too.

Considering the cost in reference to the hardware, and that I can use it basically forever, and that it's a lower distortion DAC than any phone? It's not bad. And it's a barely-noticable addon for my headphones that just lives on the cord.
