SED 6550c Vs. KT120 Vs Treasure KT120Z OUTPUT TUBES

[Nooshinjohn]

Have you ever tried any other output tubes in your amp? You might be surprised. Just saying........

My amps were designed with the KT120's in mind from the start. I can run the 88's or 6550's if I want but I worry that some of the dynamics I currently have may be lost. Right now I am so content with the sound I get from my rig, I see no need to change a thing, though Usher Dancer 2's might be something I would think about if the right deal were to come along.
