great monitors! I use to myself. Although don't expect to much of the low end! I blow one up listening to drum and bass music at good level. Yes also your KRK's can break.
I use a CI1 as interface on my laptop. There is a hum somewhere and I remove it from my recordings using Audacity, my recordersoftware of choice. Most of the time it works oke, and for listening... only a real life woman sound better in my ears,...
