4066's. Eat em up, Yum

4066s?

Great description. I feel very much the same.

I have never used these more expensive devices (so I can't compare),
but I've used lots of CD40xx switches and never had problems with signal
quality. (When I needed more than 15V, I used discrete FETs.)

Now for crosstalk. There might be applications where the C's in these
analogue switches cause crosstalk even in audio circuits. I guess
it's a tradeof between distortion (Make your audio path high impedance 
to avoid effects from varying on-resistance ...) and crosstalk (low
impedance
reduces the effect of the C's). So a T-Switch would be a good thing for
sure.
But why not build a T-switch from a CD4066 ?
One gate at the input, one gate at he output, one gate from the middle
connection to GND, and probably the 4th gate in the package used as an
inverter to control the middle gate. 
No idea how *much* this would reduce crosstalk, but I think it should
work
very well. One gate for the price of one 4066 is not tha bad, no?

Just an idea.
