new kt 90s any good ?

I'm looking for a quad of Ei KT90's. I have heard these and I think they are some of the best tubes I have ever heard. The Gold Lions are supposed to be the cream of the crop. If I can't get a set of Ei KT90's I will go with the Gold Lions. I have heard the EH is repectable but not as good the Ei or the Gold Lions.

My 2 Cents Worth

Have you had any reliability issues with the gold lions ? Thanks, chris

hi, I can’t believe so few people have used or tried the new EH kt90s, It would boost the power of my Rogue Audio M150 monos from 150wpc to 180 wpc, which could be helpful since I use revel speakers, thanks for any advice, Chris

Well you can be the first. I've never heard the EH KT90, but have heard they pale in comparison to the EH KT88. My favorite octal power tube of all time was the Ei KT90, but they are long out of production and difficult to obtain at reasonable prices.

Chrissain,there's a lot more difference between the M-150 and M-180 than the tubes.I doubt you will get the results you are looking for by just adding the KT-90's.Just my thoughts.
