Worked with servicing quad VTRs for decades. Signal to noise was limited by transverse oriented oxide (until 3M 8250 High Audio stock came out), and pre-distortion correction circuitry wasn't in place in earlier machines, but frequency response was quite good, wide band and typically similar to broadcast audio decks of that era. Viewers in the major markets of NYC and LA heard GREAT audio at home from quads. The rest of the country? Not so much, due to the horrendous limitations of AT&T long lines audio in those days. Most studio master quad tapes contain surprisingly good quality sound.
