Better sound from 6550 or kt88 tubes in Jadis amp?


I have only used kt88 tubes in my amps but they also accept 6550 tubes.

Can anyone tell me if there is any improvement going to 6550 tubes ?

hmmmm.....
I have a very early Defy 7 (s/n 213). It was originally designed to use to use the EL34 tubes. It was modified in '91 to accept 6550 and KT88's.
I also have a Jadis Orchestra Reference that I am running Gold Lion reissues on.
The JOR sounds magical. I am still working on getting the Defy up to speed. I bought some reissue Gold Lion KT88 tubes for it and when I bought it, it had JJ KT88 tubes in it.

So, If I try so EL34/6CA7 or KT77 tubes, will I have any issues or are they pin compatible with KT88 tubes?
