No one mentioning Sylvania tubes, while I think they are really good.
Here's the link to ebay seller:
In case link didn't work here is the name of the product:
Sylvania NOS/NIB JAN CHS-6AK5W/6J1/EF95 tubes
I'm still interested in knowing if there is anyone besides me who tried those, and what are the thoughts
I've tried the Sylvania JAN-CHS tubes, but did not care for them much compared to other tubes.
I tried to find the right headphones to match up to them, without much success. They did sound best with the Audio-Technica AD2000X cans among those I tried (the others I tried were: Denon AH-D7000; ; Audio-Technica AD2000; Senn HD-800). Everything seemed to lack bass, and I am definitely not a basshead. Also one tube was very microphonic.
Perhaps they just needed some burn-in time, which I did not really give them. I immediately switched back to Telefunkens.
I have also had great results with Cifte, Mullard and Russian/Voskhod tubes.
