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

I have preferred my Telefunken ECC803 tubes in my ML1.1s, but I think one of their main advantages is their longevity, the sonic difference being noticeable but not a huge improvement over the already good sounding tubes I had in there. I remember asking this question in the past and the question asked back at me was what is that you want to change...I think that's something you really have to ask yourself. If you like the sound of the stock unit, I guess you should think twice before shelling out the big bucks for NOS tubes. On the other hand, if you have some spare NOS tubes sitting around (having just sold a 12AX7 based preamp and amps I had a load of leftover and new spare Teles), tube rolling for the Lamms is a simple exercise.
