Please, what DAC is this?

Is there a prize for the correct answer?

It only has a BNC connector and nothing else?

The prize is feeling superior to my intellect.  It has a BNC connector, L/R RCA out and of course IEEC power connector.  It's normal in that manner.  Thanks

Just guessing based on your description…Audio note DAC zero? They specialize in limited inputs and kits are/were available. Perhaps you saw a custom build?

Could be a Zanden dac 

Thanks for the responses.  A picture really is worth a thousand words as this would be solved in 5 seconds.  I'll call off the search.  It's not a Zanden.  Thank you all.  Cheers

Found it!  Audio Sector DAC-1.  Usually came mounted on a piece of wood naked. Found reference to it in one of my old posts.  I know, nobody cares.  Cheers

Mystery solved. You're probably relieved in way like when you finally remember the name of that person you attended school with, and you just ran into at the supermarket. 😀
