Actually its ridiculously to try to verify this small phase responses
with
speakers. Just twist your head slightly as some one here previously
mentioned.

I don't agree with that - sure there are phase shifts inherent in the
speaker design (and amp and preamp), but they will be a constant for any
one speaker so that will result in, say, a 10 degree shift at the 10th
harmonic of a hypothetical waveform. Does this mean nobody really knows
what a square wave sounds like?

In my humble opinion we are venturing into "gold-plated mains connector"
territory here.
