I don't have any measuring equipment. Simply you can hear it. It has low inductivity I measured 0.5uH. The treble is like rounded, free from any edge or how can I describe it. Very slightly rolled off. Try it and you will realize.
A microscopic change, if any.
Very much doubt expectation bias does not cover it.
Slightly rolled off treble is easy to measure: just apply 20kHz signal, measure acfoss tweeter legs, connect 0.5uH inductor in series with it and a switch shorting it.
Let somebody else do the switching not letting you know which is which.
You should guess right significantly more than 50/50
You can use a simple $10 multimeter (which does NOT reach 20kHz) by fittting an "RF probe" before it, which turns high frequencies into easy to measure DC
We are not hunting for precise measurements, just variations: does HF voltage drop significantly or not?
If not, there is nothing to hear.
PS: if the inductive resistor is inside an NFB lopp, such as in ballast emitter resistors, there will be even less to hear, NFB erases it.
