Let me first state that I have little to no scientific experience. But hold on now. Sound travels at 343 meters/ second at 20 degrees C, or 68 degrees F. I would guess that an average listening distance between speakers and listeners ears is close to 3 meters. At that distance the sound from the speaker would reach your ears in less than 1/100 of a second. It seems to this science layman that a few degrees of ambient temperature variance would not render any speed of sound difference detectable by the human ear.There may be other variables involved that Audiogon's mandarins of science can enlighten us about but I tend to agree with the post of pbb, "Maybe your ears are affected by the weather."
