I'm also interested in the dual AK4399 implementation.
Let us know how you like the DAC. Any comments on parts quality will be appreciated.
Hi Jaffar. I keep you informed, just received the DAC from China. There's another thread discussing this particular DAC also:

Hallo
I allready got DAC 9! It runs great on the coaxial output of my Denon DCD 1560 😀 happy!
This may be a smal problem for You. - The cm 6631A module is new. What way round does it fit in to the "motherboard"(DAC 9) ? I am 60 now and got bad eyes 😱
Thank You!

gabrie: I just removed mine (unsoldered it). look for a square pad on the base board and also the riser. square pin is the index or pin-1. for me, on my lower end usb module, the square pin is near an led.
Hello, DAC9 needs 10 pins USB module,
and they are different direction
Chip of CM6631A on the module need to face to chip AK4399, your picture is correct.
but if you upgrade to XMOS in the future, chip XMOS on the module need to face to usb socket on the dac9
hope can help you
Hello,
the picture is DAC9 , but please note some sellers copy my board, such as I never use red color pcb, they are different quality PCB and components
please be careful, hope can help you, thanks
Hey guys! Currently running a DAC5 + CM6631A in my chain. Do you consider the DAC9 worthy upgrade?
Whats your fav OPAMP for the DAC5 or DAC9? Is there something like a mod list?

Hi Weilian, nice to meet you here. A question about the Dual version; Does it have Volume Control?
I got different answers from the sellers on eBey! Even those mentioned "Preamp"

I like the burson's in my dac5, along with an LM49729HA in the servo, but the opa627 weren't too bad at all in the I/V section either. That one was a suggestion from another member here as well.
You might go search out the dac5 thread for that one, although I think they look to be very similar, as I'm sure you've noticed. The dac5 has to have been the most overlooked of all the Weiliang dacs IMO.
The driver issue is more of a cultural issue regarding intelectual property, also helps to prevent what happened to me when I purchased a copied Weiliang usb board from an auction site a while back.

you do realize that opa627 is 99% chance of being faked, right? I would never trust china to send me an opa627. not in a million years.
When I bought those a year ago, I was willing to believe the same as you have claimed.
What I received was from the same vendor as the dac if I recall, and sounded way better than any of the others I had rolled. There was a quick ohms test that passed as well.
But yeah, good luck, you'll need it trying to get legit parts from random sellers. I would be a bit nervous at the thought of finding more of those.

those that included 100% not the originals, but when buying replacement needs will also closely watch an opamp. ebay is full of fakes

can someone who has the actual schematic for the dac9 (not software based dual dac, but the single ak4399 dac9 board) send me a copy?
I've asked the seller I bought it from, but they sent me the wrong one and when I pointed it out, they claim they don't have anything else (sheesh).
