I recommend buying a better amp and using a good quality tube. I've tried using the "best" tube in amps and preamps for which I had some fundamental complaint, and expensive tubes never resolved the issue for more than a week after the initial blush of the "best" tube wore off.
On the other hand, where I fundamentally like a piece of gear, then I have enjoyed installing better tubes. But, I continue to enjoy that gear whether it contains the best tube or a good tube.
My two cents. Jeff
ps. Of course, choosing the next amp is the fun and treacherous decision.
