No sadly I've not, :/
I'll put it to you this way
If you've owned a tube amp an your into the "tube" hobby grab the Starlight, an be ready to adjust your bais daily, an try at least like 10 tubes in a week to find the right one! Oh an don't forget about rolling the Op Amps to
you'll need to customize that to once you find the right tube!
If you have not owned a tube amp, an you've never rolled tubes or op amps an your not crazy about having a small collection of tubes, go with the Vali 2
Really in all honesty the Schiit Vali 2 is to Hybrid Tubes what the iPhone is to Smart phones, an the Starlight 2 would be the LG V10
With one, you NEED to customize it to get the VERY BEST out of it, an it's a heck of a great amp to tinker with! The other, if you NEVER changed a thing it would still be an awesome value
The Starlight demands that you customize an tinker with it to reach it's best,
the Vali 2 has options to build on an already established base
That said, if your willing to put in the time an money needed to find the right combination of tubes op Amps an gain settings, the Starlight will out shine the Vali 2,
if how ever you lack time, or just want a simpler amp to own an operate than the Vali 2 will suit you better
These are like legit an apple vs android kind of face off imo
