I’m a big fan of tube amps, but when it comes to sheer power, watts are watts. There’s no magical "tube watts" that’s going to make 50 Watts act like 100 (etc). And as for tubes’ famed "soft clipping" -- a push/pull tube amp with feedback (typical) can clip hard too, if you push it too far.
The reason you get a mythology of "tube watts" has many facets. For one, tube amps typically have higher gain than their solid state counterparts. Sometimes much higher. Especially "per watt". So on the same volume setting (on your preamp dial), a lower powered tube amp may sound much louder. But its peak loudness will still be limited by its power rating. The gain tends to be higher thanks to high gain input tubes like 12AX7, 12AT7, 6NS7, and the lower amounts of global feedback used in tube circuits -- more feedback reduces gain and many Solid State amps use LOTS of it because it improves the spec sheet (arguably at the expense of sound quality).
Another reason for the mythology -- tube amps typically sound great to the very last watt! Solid State gear can be all over the map. Some sound bad at low volumes, others sound bad when you start to push ’em, Some sound bad at any volume 🤣
Maggies are a classic match with Rogue tube amps. You a get lot of tube power for the money, all built in the USA, and with fantastic customer service. They’re not as sweet sounding as other tube amps, but their dynamics and bass are a thing of beauty. M180s (180 Watts /ch) or Apollos (250 Watts /ch) would be perfect, but even a Stereo 100, Cronus Magnum, or Atlas Magnum would be great too (each 100 Watts /ch). When you get enough tube power -- real tube power -- it’s amazing :)
