Speaker wants 100 watt RMS. Is 40 watt tube OK?

Now it's my time to crow; everything is just like I said, "Tube watts are louder than SS watts, plus they sound better"

Also, the room is the dominant factor; unless you got a huge room, you don't need all them watts.

When I'm right, I let everybody know it; but most importantly, we have another contented audiophile.

Tube watts vs SS watts; who you gonna believe; a formula or your ears?

BTW, they definitely do not sound the same; the tube mono-blocks sound much better.

I had a 150 watt SS amp in my listening room, and now I have 70 watt mono-blocks; when it comes to volume, there is no difference.

Many people have said the same thing; I earned a living as an electronics technician, so please believe me, I know all the formulas.

I have PrimaLuna mono-blocks that put out 70 watts per side, and 92 DB speakers in a moderate room, and I'm quite satisfied.

They can play much louder than I want them to. I like jazz, as opposed to rock, if that makes a difference.

No matter what anyone says, 40 watt tube approximates 100 watt SS. The size of the room is the dominant factor in this equation.
