# watts alone says little about an amp other perhaps than how loud it can go with a particular pair of speakers depending on how efficient the speakers are before its published total harmonic distortion specs are exceeded (assuming those are accurate).
All the other things that go into designing and building the amp, including the details beyond THD that determine how the amp really distorts and sounds is how.
