I do this for a business, so I need the best. I like to use the following jazz track because of the intense piano passages. If your system does these well, without halos, echoes, reverberation or sibilance, then you have arrived:
Gene Harris - the Concord Years, disk 1 - track 2, 4 and 6
Great piano and string bass - very dynamic.
