Anyone ever hear the DAD-NewOntech DA-30 Tube DAC?

Farfignugen,
A close audiophile friend stumbled across this discussion and made me aware of your interest in NewOntech Dac 30. I am the owner of Ole Nielsen's personnal 's Dac 30. Have owned it for a good number of years now. A tube rollers dream.

Kind of you to introduce yourself...still haven't bought a reference DAC..   Getting by with a wonderful Taiwanese DAC (some 14 years old) that uses the 2018 Sabre chip (Eastern Electric Mini-Max+)...turns out its the equal of my previous $3500 90's Ladder DAC....(& at 20% of the price-used).. 
I'm quite interested though in what you've been able to learn from hearing your Danish tube DAC  in relation to other things in the market. ...if you care to share?

Also...can you recommend a great Choice of 6922s? And why?
