I just purchased a Stax 009 and Woo WES amp and need a DAC - what are the obvious choices in the $3 - $10K price range?
Depending on what your needs are the Ayre Acoustics QB-9 is top notch.
I am not sure if you are hard set on the amp you have because the Headamp Blue Hawaii SE is my preferred amp for the SR-009.
But the BHSE a year backlog - which is crazy!
Believe me, it is worth the wait.
