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?

This is strictly my opinion/impressions

Having owned some SS amps SUMO, PS Audio, Hafler, ML33, ML 33h, ASR Emitter II over the past 20 years I have made a switch to tubes. Have settled for a 211 SET and am really enjoying it. Its 18 watts of pure bliss.
Friend brought over his VIVA mono's as well as his MACTONE.
The Viva's were great and the Mactone was nice at lower volumes.
Do most of my listening around 75 to 85 db, above 95 getting a little loud for me
For me the music that comes through the tubes is much more involving. In my case anyways.
Was really curious on having a SS power house amp in with my 18 watter.
Reading HP's review, decided to try a pair of 1000 watt Brystons mono blocks.
Had them on loan for a week and they disappointed me to say the least.
This is not to say that a SS may not reside in my home but for now I am converted.

YMMV.
