Black Ice "Glass FX DAC"

Good day all,

Spent some time searching for any info, experience or reviews on the forum here on the "Black Ice Glass FX DSD Wifi DAC", but hadn't found anything.
Wondered if anyone has experience with it, it's various modes (Wifi, USB,Toslink), and if anyone has done some testing and measurements on it?
It features 2, 12AX7 tubes on the output RCAs, which I believe you can "tweak" by switching tube types to get a different 'sound signature'.
Curious how this rates and measures up against other "tube dacs".

Many thanks
