Cayin vs. Primaluna Tube Integrated Amplifier

Greetings to all. Anybody had the chance to own both or hear both side by side with same equipment and, possibly, exactly the same tubes (not only same kind and brand but exact tubes being rolled from Cayin to Primaluna)? All the best

Here's where for no particular reason I usually insert a plug for Jolida, but since I have no particular reason to do so, I won't.
