Lamm ML2.1 Tubes


Hello, I run the ML2.1 with the tubes from factory and I am interested in opinions about using it with NOS Tubes.
Compared to the stock 12AX7 I tried NOS Telefunken 12AX7 and Mullard CV4004. There are differences, but nothing dramatic (in my opinion).
Are NOS really worth it (in general) or did someone find the match to go?
Thanks

So far, the Tele 12AX7 ribbed plate is best in my ML2; many others prefer the smooth plate Tele, but I've not tried that yet. I like the Mullard CV4004 in my phono stage, but did not think to try it in the Lamms...hmmm.
