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 ?

KT88 and 6550 tubes are not the same. KT88 tubes are what is known as a kinkless tetrode and the 6550 is a pentode. What was your amplifier designed with?
