jj 6922 vs jj 6922 gold pins

Anybody compare these tubes. I'm going to try the gold pins or the cryo treated non-gold pins. Just wonder if there are important sonic differences.

historically the gold pins were the premium offerings - meaning longer life and more importantly lower noise. most NOS tube hounds will happily pay a premium for the gold pins, no questions asked.

don't mean to be elliptical or cryptic - hell ya
Thanks for the info.

Tubes can also be low noise without the gold pins. From everything that I have read and from my own personal experience, gold pins do not offer any sonic advantage. However, they are more resistant to corrosion.
