Tube Power vs Solid State Power


I continually hear Tube power is more powerful than Solid State Power. IE; “A 20 watt tube amp’s power is like a 60 watt Solid State Amp’s Power” and so on… Is this true ???

I always think of the “What’s Heavier, a pound of Feathers or pound of Rocks story?” A pound is a pound right ? 
Maybe someone could offer some thoughts and explain if this is true or not. 
Thanks

You know larryi2, that is a good representation of what actually happens, as I understand it. The type of harmonics are the perfect imperfection that MY ears lend themselves to. Most SS are Brittle, Harsh and (seem) bright, to a point of fatigue. Tubes just don't do it..

It is how they measure distortion, and how much distortion there is at any given time. THEY (manufactures) do all kinds of things to print a bigger number, or lower distortion ratings.. There are a LOT of weird numbers flying around for sure.. 

I like when a manufacture says. 100 watts minimum @ 8ohms. 20hz to 20khz with .01 THD/IMD

A watt is a watt, it's AFTER the fact anyway...

Calm down OP, no one is picking on you, you have to meet the gate keepers, don't you? Some SEEM grumpy, they are all a pretty good bunch of folks.. :-)

Remember this if nothing else.

To whom should a gift that is being returned, be returned too?

The giver of course.

You DON'T have to receive or accept anyone's insults (or gifts as I call them) if you don't want to.. I THINK the lead pipe would hit the bottom first, BUT that is just me being the class clown..

Welcome OP.. Enjoy.. ASK away...

Not true because amplifiers do not put out power to the speakers -- speakers consume power.

Well for the sake of understanding, ay. I mean do you think an Air conditioner, cools the room, or removes the heat? :-)

This is what we like to call an airtight argument. No two ways around it. Tube watts and solid state watts are not created equal. The only question now is which tends to sound more powerful than the other? Tubes. Hands down. Not even close.

It has to do with the harmonics and what our ears/brain perceives as pleasant but in fact it is distortion. We hear it as total volume with odd order harmonics where many SS amps are voiced and leave even harmonics in. BRASH, bright, hard all the things feed back, controlled distortion and odd harmonics cure..

Pass is pretty close Watt for Watt in that sense.. Volume for watts burned.. pretty close..

What that WATT sounded like, when it was used, that's a different story.

THEN not all watts are created equal, ay?
