Rectifier Tubes 5AR4 : New production vs NOS
Hello,
I am currently using a 2005 Cary Audio SLI 80 signature integrated amp. I had been using a new Electro Harmonix 5U4 rectifier tube, but recently was able to try out a new SovTek 5AR4. I was amazed at the meaningful sound improvement a different rectifier tube type can have on my amp. Now, I am considering investing some $ in NOS 5AR4's in the hope that will improve the sound further. However, my assumption had always been that the biggest impact NOS tubes will have over new tubes are in my preamp & driver tubes (6922 and 6SN7), since for these tubes are in the path of the music signal & they were much better made back then than the current production tubes. Would love your thoughts/experience on whether there would be much of a difference between NOS vs New 5AR4 rectifier tubes?
If there is already an extensive thread on this topic - pls point me to it, i haven't found one yet or i might just have missed seeing it online somewhere.
Thanks for your help.
