My system is failry bright. Primare I20 into KEF Q5 speakers via a DacMagic. I play digital files exlcsuivle - but all lossless.
I have some cheap Silver cable from Richer Sounds. I used to have some nice Kimber and Chord stuff at my old place but it was roued under the floorboards!
Anyway, I know the Primare is kind of bright and the Kefs are nuetral - I don't want t change those so just leaves speaker and interconnects.
I've also got an Arcam airDAC on order but that probably won't help.
