Thank you!
My system currently is a Lumin T2 (Shunyata Alpha NR V1) and Magico A3's.
I demo'd the Diablo 300 on Magico A3's when I first was putting together what would become my current system. That is the only reason I was comfortable ordering the 333 unheard. But it was a few years ago and I am convinced I won't be able to give a detailed A/B comparison, unfortunately.
