Thatís why I bought several sets for my Ref 40 when I bought mine. There was a very obvious difference in tonality imaging dynamics etc in my Ref 40. Rated to 10k Hrs they last at least 2.5 times longer.
My sets are so tightly matched between A/B sections and each other - less than 1.5% all 10.
I just pulled them all for annual pin cleaning with Kontak and tested in my Maxi-Pre tube tester and still have same specs as when NOS when I first installed them.
