high power tube amps vs ss

It's important experience, but smarter to switch back from tubes.

Winggo, if you post which particular speakers you are using or have in mind, members will be better able to give opinions or advice. Some also just seem to have a personal preference of one over the other.
I happen to have ALWAYS preferred tubes by a wide margin. That goes for guitar amplifiers, as well. Some prefer SS for both. It is well worth your investigation, otherwise you will never know what you may be missing.

What is to be lost are large amounts of cash chasing after the "perfect" tube of the month, in buying NOS tubes that "test well" but are near the end of their useful lfe etc etc.

Schubert does make a point in that high power tube amps do use MORE tubes. Unless you are prepared to go with different speakers, as in very high efficency, low power amps use a much lesser amount of tubes. Then of course, some of those tubes can be a bit more expensive, tho they DO last a long time.....
Schubert, now why did you have to go and open up this can of worms!!!

Winggo, much more important than your speakers’s sensitivity is its impedance. If you have low efficiency speakers with a benign impedance, you can solve any power issue by adding more tube power. If your speakers have either too low or too demanding of an impedance curve, then tubes are not recommendable, regardless of power.
