I bought one a while back, save your money. Rolled off highs and pack of low level detail. The ESS9038q2 dacs sound much better.
do you know of any cheap good R2R dac ? found another on ebay

I'd be a little concerned about the buck regulator there to feed the digital part. Not that switching supplies are bad in themselves but they're tricky to get right in terms of layout and filtering not to interfere with the SQ.
Abraxalito , i´m a subscriber of your dac threads , if you ever come up with such project count me in as a buyer but my soldering skills are poor , it would have to be a simple kit or finished board 🙂
I do have one or two ex-demo versions of my PhiDAC-SE available. Send me PM if you're interested.
The buck regulator could be replaced by a linear reg but it would then get hot and need a heatsink most likely. If you could figure out how to mount the heatsink you could replace the switching reg. I just flag it up as a potential issue as Chinese PCB designers aren't widely acclaimed for their mixed-signal layout skills, in general 😛

Definitely sounds different from delta sigma dacs I own , less high frequency presence without being muffled , less "digital" , next I will replace opamps with AD797
