Why do NOS Tubes sound better than new tubes?


Is manufacturing really that backwards in todays techno world? What is the real reason that todays tubes cannot equal the tubes of yesteryear?

That’s funny, I asked this same exact question to a local high end audio shop nearby. "Deets Sound Room" in Carmichael, CA if you know the shop. I was giving pretty much the same answer as everybody here. But I bet if you ask that same question today to tube makers, will they give you the same answer or will they give you some marketing spill??
I was personally thinking myself tubes made today would be better than the NOS due to manufacture process today could produce a better quality tube. You would think its being built better today, but I guess that’s not what I'm seeing to all the answers. No pride in tube making today I guess.
