1K dac

hi

actually I don't need an usb input as I will feed this dac with the coaxial out of a squeezebox touch.

I wouldn't mind going on a used one, even if it's really old.
the only thing that matters is the sound quality.

my budget covers everything under 1K$

I saw the ack dac 2.0, It doesn't seem to be very popular nowadays, but I found a lot of thread around 2005/2006, what do YOU think?

thanks for reading
