Shorter speaker runs or shorter IC Runs...Which is the better set up and why?

Hello all!

So I am setting up 2 Bryston 28b Mono Amps and I would like opinions on which is a better way to do it? Should I place the amps close to the speakers with longer XLRs/shorter speaker wire OR longer speaker wire with a shorter XLRs and why? I think I know what conventional wisdom says but I am looking for the best option.

Thanks in advance!
