Quietest camera with good quality ?

I am after a camera with completely silent, or very quiet shutter. It also needs to have live view.

It is mainly for event shooting where I want to be unobserved as much as possible.

smaller is better

My shortlist is currently:

1. Sony RX100 - great all round, just deficient if I want to minimize DOF

2. Fuji X100 - not quite silent but very quiet. Fixed lens

3. Fuji X-E1 and 35mm f1.4 - not quite silent but very quiet. The best picture quality probably. The most expensive, the lens makes it slightly not pocket size

4. Canon G1X - slow AF and zooming. Not so small but nice

What do you guys think ?

Any other suggestions ?
