Made for each other!

The headphones can produce the detailed music from the Sony amp - throbbing bass (you can feel the skin of the drums!), natural voices and clear notes from the instruments.  You can know the location of the instruments.  The bass does not overwhelmed other frequencies. Peaks and valleys of the music do not break nor hiss - they are helped by the quietness of the background.  I could not hear electrical hiss, the amp is so unbelievably quiet and as a consequence enhanced the music and vocals.

I brought them to a few hi-fi enthusiasts and they were astounded!
