-or perhaps 25%.

Above those power levels the higher ordered harmonics start to show up, which is the source of the 'amazingly dynamic for such a low powered amp' thing you read about so often in comments about SETs.

The higher orders are used by the ear/brain system to sense sound pressure. Its the transients where the power is needed most of the time; when the higher orders show up on the transients you get 'dynamic'.

IME, in about 90% of all audiophile conversation you can safely use the word 'distortion' to replace 'dynamics' without changing the meaning of the conversation.

But with 106dB you'll be in the ballpark :)
