Lamm L2 Reference tube recommendation

Tvad said, " he might select tubes based on availability." I'd say seven out of ten times that, and price are the primary factors in a manufacturer's choice of stock tubes.

I bought a pair of Mullard NOS 12AX7's for my ML 2.1 (circa 1957). The sound was good but very mellow and laid back. Cymbals sounded like cymbals when I put back the chosen tubes by Vladimir. Trust me he knows how to voice his components and IMO tube rolling will produce different sound. What the listener needs to ask of himself is "Am I hearing something different or am I hearing something better?"

The man is a genius

I had opportunity to have on loan his newly released ML3 Signature amps and IMHO there isn't a better amp in the galaxy. Now if I had $140K lying around I would buy a pair in a heartbeat
