  Sorry for the belated response, I was away from civilization.
Keep in mind that you'll need Hi-Fi VHS recorder, regular ones do
linear edge recording and have terrible quality.  Dubbing is done
this way in most cases.  Stereo VHS recorder uses 2 helical scan
heads (rotating heads like a DAT apparatus) and in order to avoid
destruction of the video does FM modulation with a ~1,3 MHz frequency
band shift, the heads are also positioned with +/- 30 degree azimuth
shift for the similar purpose.  This is all very simplified by me to
the point being bordrline primitive and erroneous explanation, but
the essence of the matter is that you will use rotational heads with
very high effective velocity and tape width, and the quality is
definitely very high enough for you be unable discern any difference
between CD and VHS Hi-Fi audio except for few of us.
