It's quite simple really, the reason manufacturers give specs at rated output, they're better. So, taking this into account, in theory, the 35watt amp would be it's most linear as it approaches 35 watts, the 200 watt amp as it approaches 200, etc. These numbers do not represent maximum output as you keep claiming I'm stating, which I'm not, these are the manufacturer's "rated" outputs, nothing to do with "music output" "dynamic output" etc. Actually I should qualify the above with most SS amps, tube amplifiers are a different breed, also some early SS amps and why JGH was initially so enamored with the Dynaco ST 120. It became more linear at lower output mimmicking the tube amps of the era when driving the super sensitive speakers of the time.
