I was embarrassed for the guy.
Didn't want to challenge him, since it's his setup.
Wasn't even an exotic setup. The "exhibit" was lukewarm and he played the system way too loud to showcase the setup.
I did get to enjoy it on other setups. I got the LP US cleaned at the Kirmuss booth by Charless Kirmuss. Kind of lengthy process, if you do the steps in his setup.
