Audio input selector

I use reed relays; not the best solution but noiseless (high quality standard audio relays are too expensive for me).

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.
