From my experience with my desktop amps as well as portable tells me that the loss of upper mid/ lower high is likely due to the output impedance of the pairings. Robert of Headphonia tested this and it became the reason why the new Arrow amps don't have an output resistor, no loss of frequencies with the Triple.Fi.
