Good 6550/KT88 tubes

Hey folks,
Can someone tell me what the sonic differences are between the Svetlana KT88 and 6550c tubes are? Also I heard that the Tesla KT88 tube is one of the best production KT88's out there? Any comment? I am looking to tube my Rogue Magnum 120's and could use the help. Any tube suggestions would be appreciated.
Thanks guys

See http://store.yahoo.com/thetubestore/kt8890100types.html and http://store.tubedepot.com/6550kt88.html for info and prices.

I'm in the same boat as you, with a new-to-me c-j Premier Eleven-A.

How about SED =C= KT88? It's said that this tube is manufactured in the same factory with Svetlana in St. Petersburg. How SED KT88 compare to Svetlana?
