Only very high Q antennas should noticeably effect audio.
Comparing a dipole to say a turnstile, you should notice
no real difference at all.
I've used turnstiles on 75 and 40 meters for years.
They work very well, but audio improvement is not
one of the usual features noted.
I prefer a turnstile over a dipole on the low bands
if I have my choice.
They seem slightly more efficient overall, but I've
never done any accurate testing. They also tend
to fill in the nulls off the ends that a dipole can show.
I've heard that running a circular polarized antenna
like the turnstile on HF, only shows circular polarization
at the higher angles. Which is what I'm usually using
when working NVIS on the lower bands.

I have though that also, but I have noticed that on 75 meters there
sometimes seems to be a differance in the voice of the other station when I
switch from my off center fed antenna at 50 feet and a dipole at 20 feet.
This is when signals are around the same on either antanna. Around the s-9
point. I am using an Icom 746pro and an external switch to change the
antennas.
