Actually no major improvement as from the get go they sounded wonderful and much more musical then stock 6n30. In the mean time i’ve plugged in also one near 6550 and exchanged stock 6550 with winged c so considering all changes it plays on different level then before..

Wonderful, I'll be swapping out stock tubes with these on the new REF6 SE.
There are 2 versions of this tube that im aware of, earlier version sporting a square getter and then the round getter that came after.
I purchased both to try, will post back with my takes on them.
