Looking for brighter tubes

I have read that the KT90's tend to have a more solid state sound and less of that tube warmth. I am sure someone will let me know if I am wrong.

Yes, that's my experience with the EAR 890.

In a phone conversation about 10 minutes ago, Mike Allen of Jolida told me that KT120s should work fine in my (newer version) JD502P. So there. Also, he seems like a cool guy.

What indicates the newer version of the JD502p?

i use tube guitar amps and have found that a good Chinese pretube adds treble and edge to my sound.... the russian stuff is more rounder sounding

Wilson667...good question...if yours is a couple of months old it's likely a current version, although of course I have no idea. On mine the labeling on the front has the silk screened Jolida name and a small gold logo badge, unlike any pics of them I've seen. The bias screws are even with the bias leds...I was told they sound a little more dynamic now, but I have no clue what makes them different other than what little specific info I've gleaned from talking to people at Jolida...I suggest you call 'em.

Also, reading that somebody has had bad luck with EAT tubes strikes me as amazing...at nearly $1400 for a "quartet" of 'em...man...
