My two favorites are: Engineer's Choice II by Delos # DE 3512 it has excerpts of John Eargle's favorite recordings. The other one is "My Disc" The Sheffield/A2TB Test Disc, Sheffield Labs # 10045-2-T it contains various techincal tracks in addition to some reference music very help full when setting up a new system or further tuning your current set up.
