Why are older tubes so much sought after


What is it with old stock tubes?? They were made years ago and surely by now we have must learned something about making them. So why are some people searching for old tubes. I have a Shanling CD player and I actually think the stock tubes are better than the 395a tubes.

Every single tube component from my stable as well as those that I owned in the past benefited from tube rolling. Selected NOS tubes were always my preferences. There ar some nice new stock tubes like JJ or GE 211 among few others but in general, NOS rules. Only my opinion.

P.S
I spoke to more then few designers and in all cases the NOS were recommended and prefered over the new stock. Lowering the production costs and difficulties in finding the right source are just some of the reasons to choose new stock over NOS.
