I've had my ESP/95X for a few weeks now and couldn't be happier! I tested with REW and MiniDSP Ears rig and compared results with my $4000 Focal Utopias and to my surprise, they actually had lower THD than the Focals! If you are even considering buying a pair of these cans, DON'T EVEN HESITATE! They sound fantastic! Best purchase I have made in years. Extremely happy!!!
