Question about wpc on tube amps


I have been kind of looking at tube amps based on what people seem to think about them.

Here is my question- whenever I look at the wpc, they are remarkably low vs. a solid state amp for the money. 

It leaves me scratching my head. Then, somewhere I read that you can't compare a tube amp with a solid state amp . Something along the lines of "10 watts of tube power equals 100 watts in a SS amp". 

What? Is this real?  Seems unlikely to me. 

Are the wildly low power ratings on the tube amps I am looking at simply due to the fact I am looking at $1,000 amps vs the bajillion dollar amps you guys buy?

Would I be better off spending the money on a tube preamp for the "tube" sound I always hear about. 

I am running Magnepan . 7's  with a Bryston amp. Since the . 7's are power hogs are tubes even a realistic thing for me in my lowish budget? 

Thanks!

Low power SETs are great for sensitive speakers.  You don't have those.

Thanks guys, you all confirmed what I was thinking. I just wasn't certain since I haven't any experience with tube gear.  I will move forward with a tube preamp!  I need a better one anyway. Besides, I never had any beef with my Bryston. It drives the Magnepans quite well. In fact, I bought it on a suggestion from a member on this forum.

Thanks again! 

I am a big tube fan and run very low-powered tube amps with some fairlyefficient speakers.  I have also heard various maggies run with tube amps, some not so powerful, and the sound can be quite amazingly good.  But, there were limitations on how loud the maggies could play with lower powered tube amps.  As for high-powered tube amps, I tend not to like the sound of such amps as much as I like lower powered amps; the high-powered amps tend to have a brittle sound.  Where higher power is a must, I prefer solid state, particularly where there are budget constraints.

I don't think it would be easy to find ANY kind of tube amp at $1,000 that would have enough power and would sound good.  A used tube amp would be a possibility, but, used gear is something someone with experience with tube gear can buy and service, whereas someone without experience might not be as suited to owning such gear.

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 :)
