The manufacturer's claims of the Nightingale speakers and the difference in quality between the 4-ohm/8ohm settings on amps so equipped are separate issues since these taps affect the sound quality driving any speaker. As a user, sound quality is the whole point for me.
I have a problem with manufacturer's using taps for reasons other than sound quality (in SS. Have no experience with tubes). Skip the taps and design it to perform well under varying conditions for about 20 years. That's just me and yet another issue not related to the question.
