If I had to pick just two to give me a rendition of how my system was performing or to audition other components, it would be:
For impact and rendition of percussions and clarity of chimes: track 3 "Posters" on Jack Johnson.s Brushfire Fairytales, CD
For richness, clarity and staging of strings: the last track "These Are The Days" on Van Morrison's Avalon Sunset, CD.
