Tube rolling with Quicksilver Mono 60s -- from KT77 to KT88? KT 120? etc.

Happy Turkey Day!  I have Quicksilver 60 Monos and I'm using Gold Lion KT77s. They sound great. The amp came with JJ KT88s and they were a bit bright/harsh. The GL 77s are better.

For variety's sake, I'm thinking of having another set to just try for variation. The monos can use KT77, KT90, KT88, KT120 or KT150 outputs.

I have heard the Gold Lion KT88s are great tubes, but I'd also be open to others (not more 77s, though).

Does anyone one have a sense of the kinds of sound changes might be brought by either KT90 or better KT88 or KT120 or KT150s?

If it matters, I'm using a QS Line stage and stand mount speakers, 8 ohm 87 db.

One thing I'm looking for (possibly) is a somewhat tighter bass, but I'd be open to hearing what other sonic changes might result from other tubes.

Thanks.

Wait until these are released

You can be one of  the first to report on sonics. Should be a turbo charged KT150.
The KT150's get positive reviews. Just not much info on them yet.

"Those are honkin' tubes. Would they work in my amp? I don't know. They're not on the list the amp came with."

hilde45- They aren't available yet. My guess is if your amp is approved for KT150, they probably will be. Until they are officially released and getting the nod from the amp manufacturer of course, needs to be confirmed.
