I always liked mobile versions of Sabre chipsets, and this is my first time with 9039Q2M.
I think this is first serious Fosi DAC and its already better than both SMSLs that I've reviewed recently. It beats them for half the price, and thats what I like: sounds better, costs less :)
You can get one here on eBay (probably preferred source for most of us):

(and try that one with HIFIZONE code, Fosi was kind and reached me with coupon code)
Also, get opamps to replace NE5532 here:
