Stahl-tek Vekian - help please!

I have a Stahl-tek Vekian DAC which has hit a problem. The guy trying to fix it for me is "flying blind" with no circuit diagrams or anything to guide him. Does anyone know where he can access some technical data to help fix the problem? (basically a crackle and hiss emerging from the right output channel)

There is a Facebook page but no apparent activity on it to help, so any suggexstions gratefully received....
Wow! A $20 M.S.R.P. Dac, and the company only has a facebook page? Okay......
Fix it society.
What planet you on?
The trash can is your friend. 
Um, from what I read it is an msrp $20,000 dollar dac.
How did it get from a 20 dollar dac to a 20K DAC?
It was a $20,000 DAC and will be a $0 DAC if I can't get it fixed.....
"The trash can is your friend."

stereo5 wins the internet!   

The Op can contact the wife, who was on all the legal paperwork

Looks like  it WAS just another fly by night operation.
That is one expensive flight....
The company has apparently been "voluntarily dissolved", which means that the owners shut it down and sold the assets, which were used to pay off any debts.

In other words, apparently Stahl-Tek is no more.  

I know I have said this before but I don't buy from botique manufacturers for this very reason.
Contact Purist Audio Design in Clute, Texas. They did most of the distribution and know where to contact the designer, who is quite brilliant.
Thanks for the suggestion. Just tried that and got an immediate reply saying that they will see what they can find to help!
Pure Audio have replied informing me that, in terms of the original design/circuit diagram there is a corrupt disc issue, so it looks like they can't help.

Does anyone else have any information that can help ? This is a very expensive piece of kit that is heading for the trash can, at the moment....
You might contact Mike Powell from Verastarr.  He knows a lot of people in the industry and he might know someone who can help you out. Good luck.  
roncalvert, the tech is just going to have to fly blind. It could be something simple like a bad solder joint or connector. At this point you have nothing to lose.
Yes, he is doing his best, but no luck so far. 

Thanks chayro, I shall try to get in touch with him
As a last resort, maybe just put it up for sale as-is, no returns. Fully disclose the issue and that the company is out of business of course. Then let the market decide. You may end up doing well. These things are out there and people may want them for parts or believe they can fix them. You can put a decent reserve on it if you’re worried about having to sell it for nothing. If possible shoot a video of the dac’s sonic issue so there will be no misunderstandings later. Good luck.
