Which Canon compact for best video / audio?

[thrumyviewfinder]

I've only seen reviews that sometime mention if audio is bad or video is but I'm having a hard time comparing Canons to choose one for better video / audio than my S400. Mainly I like to record concerts. The video has been fine for casual daytime stuff but in a club it's horrible.

My price is flexible so if you love your camera let me know which model it is!

I'm partial to Canons but may consider another brand.

Thanks a lot.
