Another discrete R2R Ladder Multibit Dac, this ones from Audio GD, their coming on strong.

Yeah, that same guy reviewed the Holo in the context of many other DACs. I think he’s kept the Holo as a second DAC. Kind of a long series of posts, but quite exhaustive: http://www.superbestaudiofriends.org/index.php?threads/life-after-yggdrasil-watering-the-ash.4036/

Some other impressions here - a long string of them if you want to read through the whole thing: http://superbestaudiofriends.org/index.php?threads/holo-audio-spring-dac-level-3-kitsune-tuned-editi...

And one other guy had a entire writeup on NOS type DACs. Can’t seem to find the post, but I know it’s there. One of the Soekris DACs is covered in another post too somewhere.

I think The poor review of Singularity 19 is because it was not burned in at all. It needs about 600-1000 hrs of burning in, I heard from audio-gd users! I am not u
sure If reviewer got a second burned in unit or not but he reviewed it immediately without playing for days at least it seems unless I missed something in the review. Too bad, I really want some reviews to compare audio-god with schiit or metrum or holospring

Very poor distortion ratings vs completion and run hot several  said board fried .
in R8,not good.
