Atmasphere,
I follow what you are saying about how a voltage source SS amp invariant to impedance theoretically would sound bright driving an electrostatic speaker. But in practice I don't find this to be the case. Years ago, for fun, I put my tonearm leads into the line stage, bypassing the RIAA curve of the phone stage. Of course, that produced very bright sound due to the 30 dB boost at HF compared to low freq. With the stat speaker, impedances can be as high as 30-100 ohms in the upper/lower bass, and 1 ohm or less in HF. This is more than the 10:1 ratio you cite, but still nowhere near as much as the inverse RIAA curve. Still, according to your theory, the stat speaker should sound like a less drastic inverted RIAA curve, which I didn't find in the listening. Also, all dynamic speakers have marked variations in their impedances, and your theory would predict that a SS amp would produce markedly different sound from different speakers in relation to each speaker's impedance curve. But I have found similar tonal differences A/B'ing 2 amps on different speakers. For example, SS amps generally sound brighter than tube amps, which I have found to be true regardless of whether I used dynamic or stat speakers. I am puzzled by my different listening findings compared to your theory.
I wasn't saying that amps don't make much difference, because obviously I pursue finding amps that offer more clarity, etc. But it is clear that whatever sonic differences there are among amps, the sonic differences among transducers like speakers are vastly greater. This is also true of transducers like cartridges which are really inverse speakers.
