All of the above true, and the biggie for me is tube's special way of delivering micro dynamics, Brits call them valves which brings to mind human lungs and breath, tubes give breath to performers.

@inna, Mapman has it right. The reason the tube amps sound like they have more power is because of how they make distortion when approaching full power. Unless its an SET, with most tube amps the higher ordered harmonics start showing up in greater amounts near overload. This interacts with the ear which imparts the impression that its louder- more powerful. This has given rise to the false notion that tube power is more powerful than solid state. But like @mapman pointed out, if you have a sound pressure level meter, you'll find that its not louder- and in fact might be quieter. I mentioned the caveat of SETs- they take this to an extreme by producing those higher ordered harmonics at a much lower power level- perhaps only 20-25% of full power, which is why many people talk about their 'dynamics' (since power is used the most on transients). But what they are really talking about and also in this case is distortion and how it interacts with the human ear (the ear uses higher ordered harmonics to gauge sound pressure). Tubes make it an enjoyable experience since there's plenty of second order harmonics to go around too. |
You've mentioned this before, and I finally got to experience & hear this phenomenon for myself. Spot on. Push-pull amps are better for me, especially since I like to listen loud. |
Put simply and without a lot of technical detail, as other have noted, many solid state amps sound downright nasty when they clip, while tube amps don't. That allows you to leave the tube amp at the higher volume even though it is still clipping versus a clipping solid state amp that sends you running to turn the volume control down. That's one of the big reasons many electric guitar players greatly prefer tube amps. |
