I seem to be getting conflicting advice in regard to setting up a system properley some people say "whatever sounds best" others say "you'll never get the best out of a system until its set up right" ie with sound meters an all ?? Is it really the former or should you get someone in the know to help with the setup? I've always preferred setting up myself but when I get my new system I dont fancy spending a packet and only getting 50% of its potential!!
