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

The three KT-88 choices are -- Svetlana, Tesla, and Electroharmonix. Svetlana is warm, full and nice. Tesla is also nice, a little brighter on top, little less warm. The Electroharmonix is too new and not much is written about their sound except a few people's comments how they like them. I have some for sale I bought and didn't use cause I switched to a non-KT-88 amp. The EH is being used as stock in the Magnum version of your Rogue 120, however.

Some guy has an ad for EH 6550's and says they are the identical tube to the EH KT88. NOT!
They may look the same, but they are not the same. Although I really didn't get a chance to really listen to the EH KT-88, I did briefly compare it to the EH 6550 and it was definitely better. I, too, did note the how similar they looked, but they are not the same.
