I've got a Signstek and it was a revelation but I've got a few quid to spend potentially and I fancy something a bit better.
Budget is below £100/$130 and it has to be usb input with a headphone output, and it will be driving 32ohm AKG cans. Portability is not an issue as it's fastened to my laptop.
I'll admit I have a soft spot for the "oddness" of some of the Chinese stuff, but I do worry about the import duties to the UK. I like a wide soundstage with a forward balance in my audio equipment and I listen to rock such as Black Stone Cherry and AC/DC.
I am not averse if absolutely necessary to buying a readymade dac board and putting it in its own box myself.
Let's have 'em!
