Should I upgrade my Tubes

I have a Rogue Audio Magnum II which is 100 Watts per channel paired with Vandersteen Treo CT speakers. My tubes seem to be shot as suddenly I get no amplification (just very low level audio). The 4 power tubes are TUNG-SOL KT120. I have been reading about getting "better" tubes but every discussion seems to get into "depends how you like the sound" types of comments similar to every other audio component - LOL.

So what's a man do ?

If your amp can accept 6550's Svetlana , go with those,, I am running the Svet 6550 in my Defy7, That tube has a  solid reputation, and I concur lives up to the hype.
The new and old are IDENTICAL,, no such thing as NOS Svet are superior to the new, thats snakeoil, and some folks are getting 2x's the price.

The 6550 will deliver all the same/or very close (= a superior balance bass to mids) bass as the 120’s, but also give you high res mids
What i am saying is
the 6550 (kt88 = same tube, but I perfer the Svet vs all other 88 labs) is perhaps the finest power tube ever made. 
and I perfer the Svet over all other 6550's
