This cues a related question I've been mulling for quite some time.
Assuming the impedance increase added by the autoformer doesn't put the load outside of the amp's desired impedance range, what are the downsides of adding one?
That is, why don't we just automatically bump up all of our speakers to around 16 ohms, and then remove the autoformer if a special case amp shows up that doesn't like that high of impedance (e.g., some of Nelson Pass's SIT amps generate more distortion at higher impedances and prefer the 4-8 ohm range)?
Thanks.
