EH 6550's?


Does anyone have an opinion on the EH 6550 tubes? I bought a couple of matched quads for what seems like a great price shipped form the Audio Pimp. Then I got the VTV issue, and they didn't even test them. I'm still waiting for my amp to come back from repair to try them, but wondered if anyone has prior experience with them. They're the fat bottle versions.
Thanks,
David

Thanks Wrayray. Jason's actually a member of the BAAS, though I have only been to one meeting and haven't met him. Interesting article. I'll give the EH KT88's a try, if I ever get my amp back.
