CD4066 off state not off enough

The OPA2134 is similar and spec'd specifically for audio but I (and my test listeners) like the 2132 better.
Just my .02

If you're doing audio, consider the OPA2132 (BurrBrown/TI). A bit more expensive than the TL07x but way better for audio - on the datasheet and in the ears. Less noise, higher slew rate and bandwidth. I've been toying with a guitar preamp design and that's what I've found so far.With the resistor to ground it works perfectly now!
Regarding the TL07x I'll keep it in mind for my next supply run.
