Power output of tube amps compared to solid states


I'm having a hard time trying to figure out how tube amp power output relates to solid state power output. I've been looking at the classifieds for tube amps and I see lots of tube amps with 50w or 60w output, but nothing close to the 250w output typical of solid state amps.

So I have no idea what type of tube amp is required for my set up, right now I'm using totem forests with a required power rating of 150w-200w at 8ohms. The bass is so powerful on these that I have the sub crossover set to 40hz.

My question is, are tube amps so efficient that 50w from a tube sounds like 150w from a solid state? Or will 50w output from a tube severely limit how loud I can play my speakers? If so, are tubes usually meant to be driving super-high efficiency speakers?

I had previously tried a tube pre-amp with a solid state power amp (both musical fidelity) and didn't like the results because the imaging suffered greatly, even though the music sounded nicer from a distance. Now I want to try a solid state pre-amp (bryston) with a tube power amp (no idea which brand to look at), but I don't know how much power output I need or if it will even be possible with my speakers. Does anyone know what I would require?

There is a scientific explanation as to why Class-A amps sound better than Class-B,but there is no scientific explanation as to why tube sounds as loud as solid state when the tube is less powerful.
I am going to jump into this "tower of babel" with all four feet and state my qualifications for doing so.
Before I became an Audiophile, I was an electronics technician who knew all the electronics formulas. "If you can not measure it, you can not hear it" was my slogan.
After I became an Audiophile, I laid my meters to rest. I can hear things that no meter can measure.
"Is this dog better than that dog"? Unfortunately, no one can answer this question but you. This is not a scientific arena, this is a very subjective audio arena.
