I have searched the forums for several weeks now because I want a good pair speakers to enjoy my music. I won't record or anything. Just listen to my music. As I understand, the best thing is to go for a pair of studio monitors (correct me if I am wrong). I have then searched / listened to some and one of the best fits were the KRK Rokit G5 (but I am open for other suggestions). Now, the question that I am not sure about is: Do I need an audio interface (like the Apogee Duet) or is it enough to just connect them to my MacPro? I have red that the sound quality and the setting possibilties aren't as good in OS X and that I wouldn't get the most out my studio monitors. So my question would be: How much loss of sound quality would I get? Can someone enlighten me please? Thanks in advance!
