I don't like analogue switches. I agree with you; CMOS are the worst (high R, small headroom,..), DG and MUX are good but not so good as relays. I saw also switches with FETs (J111,etc) but didn't try.

Thank you all for your ideas. I think I'll go with moamps design. Yes, the cd4066 is rather old and noisy, but the other switches you've mentioned are hard to get and/or expensive here. Any other ideas about switching? Maybe another chip? How about tda1029? It has everything one could need, not sure about noise though.
Nothing is as simple as it seems
