I was talking about -b 64 or -M 64, not -q 0.  This is an important
distinction to make.  Whilst I wouldn't call -q0 transparent, it does sound
pretty good considering what it's trying to do.  -M 64 on the other hand
sounds quite dodgy, (you can really hear it breathing), and -M 56 and -M 48
sound much worse.  But apparently RC4 will sound much more acceptable and
consistant.
