It must have been your source.

The square wave response of the Abyss surprised me - I would have guessed that a membrane responding to a magnetic field would be much faster than a voice-coil driven dynamic driver, no? And, if the single sided planar in the Abyss is claimed to be more free of reflections than a typical planar, then I would have guessed it would have *better* transient response, not worse. Then again, the stock T50RP has a pretty bad response to square waves, so clearly I don't understand the factors involved.
