Eh? What kind of SS amp has an ouput impedance of 4 ohms? Mostly they're well under .1 ohms (usually expressed in terms of the damping factor). An amplifier with an output impedance close to the impedance of the speaker it's connected to will audibly distort. > Yes, this is a whole 'nother matter - LC effects.
