How come that NOS is better them NS new stock ?


There is a lot "tube equipment" threads on this forum. After hearing some good tube amps, Lamm, Hovland, BAT, Cary I could understand why people are buying and making so much fuss about it. I with every passing months closer to invest some money in "obsolete" technology :)
They really sound better then their modern SS counterparts. But I do not understand why people at any price are trying to replace their NS (new stock) tubes for NOS tubes. Do not we have progress in electronic industry? I believe that nobody is using anymore black and white TV, old picture tube should be better then new ones, is it not? But people seems to buy instead, new ones...
So how come, old tubes seems to be better for everybody here? How|Why they sound better?
Maybe SS on old germane transistors form 50's would be better too?
Maybe old resistors would be better too? It does not make any sens to me.

This is old post, from Tube Asylum that could to some extend answer your question:
"This is mostly economics, IMHO, the more people who buy tubes
and they more money there is (and more competition there
is), the better the quality control gets and the more
effort is made to make better tubes. And indeed that's exactly
what's happening now.
40 years ago, a lot more tubes were being made for audio
purposes since nearly every audio amplifier from kiddie phonos
to stadium amps used them, and the large companies that made them
(like GE,WE,RCA, and Philips) could bring much more financial & engineering
resources to bear on the problems of tube design & QC than
today's smaller concerns can.

The other problem is that there's so many variables in
tube manufacturing that even if the same companies came
back and tried to make exactly the same tubes, they wouldn't
come out the exactly the same. Maybe close enough to
make most people happy, but you'd still get people saying
they could hear the diff.
I think the best you can hope for at this point is that
the current makers make the best tubes they can, in some cases
the results have been pretty impressive. "
