Is it true that a solid state amp doesn't need matched impendance?
I guess that depends on what you mean by "matched impedance".
If you have an impedance mismatch on the input you can get distortion.
A solid state amp can tolerate a higher impedance load on the output than specified (ie: if it's built for a 4 ohm load you can drive 8 safely). If you drive lower loads, a good amp will shut down safely and a bad one will fry.
Stuff I've been told-
As I understand it a tube amp is just the opposite- it can tolerate a lower impedance without damage but not higher. They also have multiple taps on the output transformer (a ss amp has no output transformer) but I've been told they are not always a very good measure of the actual impedance.
