Is this statement from @atmasphere above true?
"At the other end of the range, the speaker is pretty low impedance (1.5 to 3 ohms depending on the position of the Brilliance control) which will cause most solid state amps to be too bright and nothing for it but to turn down the Brilliance control and deal."
That is, if it's a low impedance speaker, an underpowered (or maybe not enough current) solid state amp will sound brighter?
