Axiom Home Page Forums General Discussion Stereo Figured out Phase while listening to STYX ?

Which of these disks would you recommend for best features, but ease of navigation. I'll also want to use the Video items to tweek my Sanyo Z2 performance.

My main concern is SPL meters, in laymens terms what is their function, and I'm curious if the people that have receivers with auto setup, still used these?

thanks, guys
