New tubes in Rogue M-180 Monoblocks


I understand the M-180s now ship with the KT-120 power tubes, instead of the KT-80. You can also simply replace the KT-80 with the KT-120 if you already own these amps. I'm curious whether anyone has done it and what their impressions are as far as the difference in sound. Is the over $300 upgrade worth it?

Just curious, but I have had a few people tell me that the "sparkle" of the 120 tube seems to wear off a bit after listening to them for a while. Sort of like the new car smell going away after driving your car for a few months. And that the 120s can be a bit harsh. They all went back to 90's after trying them.

I take it most of you are not getting this?

I've not tried any 120's in my demo gear here. I may need to just purchase a few and see how it goes.
