the vast part of break-in process of the new tubes is when you idle them for almost two hours with no input signal. the second and further times you will have to follow the instructions suggested by manufacturer on how long you should worm-up the tubes before you listen. the rest will come with time. i might mistake to say that it's more matter of personal adaptation rather than some physical electronic process takes place, but imho i can't find any other explaination.
Do new tubes undergo break-in like other devices?
I just put a new pair of Mullard Ecc34 (should be 6sn7s) tubes in the r/l inputs on my BAT VK60. These are the 2 most importants positions for BAT amps.
Part of it sounds wonderful...back of the soundstage, instrument separation, dynamics, articulation in the bass. Oh, and much queiter.
However, I don't think they have as much gain, I have to turn up the volume some on the preamp, and the bass is much lower vs the other parts. Kind of like a new power cord...needs time to open up. I can deal with the gain, not sure about the bass. This may just be a system matching thing, works great for some, not for me.
Is it break-in related?
