Just finished my dac, but I have noise on the single ended output that i'm still troubleshooting.
What noise ???
can you describe in detail ???
Thanks
No , I have not started yet, don't know how to do it , but I expect some help from the designer.
What do you want I hepl you now??
dear Quang Hao,
the dac works only with cd optical or coax , when streaming dsd get strange display , what could that be ? and no sound !!!
This happens when you turn on the power switch too quickly and continuously. LCD takes 10 seconds to reset.
Thanks
Very sad day for me , connected the DAC and I got smoke, I knew it this was coming . Now Troubleshooting nightmare!!
You can sent all to me??
I will finis all free for you??
Thanks
I'm blind, I don't see the price of the Tube output stage??

thanks
