Hi. I'm from Malaysia and have two questions:    a) What is the warranty period of the unit? How do I get repairs done if something is faulty with the unit during the warranty period?  b) Is the performance of the unit the same using the USB sub card with XMOS program or using the U12? Will I get a better performance using the U12?    Thanks.

24.04.15 13:41 Asked.

It have 1 year warranty. You can ship it back for repair during the warranty period, but you have to assume both ways shipping fee.  Work with U12 is better. Thanks.

X12 USB has stopped working. I did try it with another computer. Can I buy just the USB board?  Thanks.

26.10.16 04:51 Asked.

Hi Jeff,    1. If the coaxial can use, computers can identify, computer equipment that is wrong  2. If the coaxial can use, the computer can't identify, change the USB card  3. If the coaxial can't use, that is x12 have problem, the machine needs repair    Best Regards  Kerwin  Shenzhenaudio

Hi I am thinking about buying an X12 DAC but wondered if the X20Pro would be much better. I don't need the additional features of the X20Pro. I just need a fantastic sounding DAC, crystal clear, sparkling treble, airy sound with good sound stage.  I don't play DSD. I have high end power amp and passive pre-amp. Does X12 sound as good as X20 and if they are different how would you describe the difference? Thank you.

22.03.17 13:45 Asked.

Hi Peter,x20pro is better than x12.But if you don't need x20pro,X12 is enough good.Thank you.
