Do you have a set of PC speakers or another headphone amp?

Try to Run off the DAC output to see if it is the Head amp or the DAC that has the problem.


Yes of course, to be honnest I mostly use the DAC with a Gainclone and a pair of Eltax monitor III.
Output and headphone does not produce sound

Are you using a Sound Card, make sure it works, your headphone works, etc. Have you done anything to the Zero recently?


I use 2 differents sources, my headphone works, my amp works.

In fact yesterday, I was programming an Iphone application and it was very late, my wife was sleeping so I was listening music with a pair of headphones.

And suddenly, no sound, I first thought that the problem came from the Mac, this morning same problem, no sound, only the relay "click". Tested also with my DVD player same problem, and I have done then a lot of tests without any success..

Yep..At the begining, received it without HDAM and Alps pot and now I'm damned.

I have contacted Lawrence, he has asked me to send him back the board to china.

Suddenly the sound was gone as I heard the relay click off, now It won't click on again - the zero doesn't work.

Any things to test to fix this? tried optical in to no avail, tried turning it on/off and letting it cool etc :|

It's a stock zero with a HDAM earth. It has acted up like this before as well, but now it seems to be final.

Look over all the components with a magnifying glass for any burn marks.

Mine was the same, though it didn't fail whilst I was listening. Used it one day, without issue, and the next it produced nothing. I checked what I could - regulator output voltages, continuity between the DAC IC and the opamp socket, and the opamp socket to the RCA outputs. Never got to the bottom of it...

Sadly, more and more of these Zero DACs are failing after a few months. Good luck getting support from Lawrence, he shafted me when a brand-new purchase was faulty out of the box...

Could be a very good time to upgrade to the Compass?

That Vendor is top notch.

It's good and I don't believe you'll have these types of problems with it. Additionally, there is great support from the manufacturer.

Read the Compass thread, there is a blurb there.

The Compass' DAC is very similar, but uses upgraded parts, so it is considerably better if not amazingly so. But the amp in the compass in in a completely different league - much much better than Zero's amp.
