We have tried the KT 88's with numerous amps that come with the 6550's and we have always considered the KT 88's to be superior from top to bottom. We have also tried the KT 90's and have still found the KT 88's to be overall the superior tube.
You are now experiencing one of the advantages of tube equipment and that is that you can change the sound of your system by changing the tubes. Changing the input tubes can also tune the sound of the system although usually not as much.
We have tried the various brands on the market and like the KT 88 STR's by Ruby Tube.
Good luck and have fun!
