Don't just use "great" sounding CDs to audition new loudspeakers but be sure to include the poorer recorded CDs you may have; the older ones that have not as yet been digitally remastered to 20 bit or 24 bit processing with the the latest state of the art remastering electronics. I always bring the crappier sounding CDs as well when I audition to see how well the newer upgraded speakers do with those. One CD that comes to mind is Jackson Browne's "For Everyman" CD. I've been looking for a newly remastered version but so far, no luck. The original is awful.
