I'm using virtual instruments such as Halion and Superquartet. Signal
on headphones is ok. but keep hearing some kind of distortion from the
cones. The KRKs put in evidence a lot of "undesired" detail (hiss,
digital quantization distortion, brief crackles, etc)... I mean not a
bad thing but I used not to hear that garbage with mi Monitor Ones or
the NS10s. I still have to try another power amp to be sure mine isnt
the source of the problem. Thanx for your help.
