When auditioning new TTs pay keen attention to pitch. From my experience and having read others reviews, it gets overlooked. Often, the impact of the music, detecting fine sonic nuances, quiet background outweigh pitch (or change in pitch) on initial listening (even lengthy listening sessions).
If you cannot detect pitch (or deviations from perfect pitch), then you have more TTs from which to choose.
