I simply cannot accept that cables are 'too bright'.  people bang on about bright this and the like.

cables are passive, not active, so they cannot add anything to the sound, only attenuate things. all cables are, are resistors, but with elements of inductance and capacitance.  so if a cable sounds 'too bright' then surely it is taking less away at the higher frequencies than one which doesn't. or, more simply is showing you what your system can do at the top end of the audible spectrum.

my first 'quality interconnect' was vdH D102.  instanltly I could hear more detail and bass. the cable wasn't boosting the bass, so the old cable must have been attenuating it more.
