For overall 1 disc to have (if you can find it) I choose Opus 1 (1st) test CD .. amazing breadth of music and well recorded .. Tiden barogue (unsure of name/spelling cut) I have found glaring distinctions from 1 system to another .. and while its not my "relax a bit CD" it allows me to quickly size up a systems strength for placement, depth, stage width & especially detail.
An all out dynamics and bass challenge would be Gordon Goodwin's Big Phat Band "Life in a bubble" (HDTracks & others) if your not hooked by the 1st track .. you need to turn it up louder.
