I have used all three. I personally think all of them are amazing and any pair that you get will be great! They all perform well and i'm guessing you've never heard any of them so in all honesty just get any one of them cause they'll sound good and then it won't matter how the others sound.
**** straight!!! Only one thing better than a set of Z6's, and that's 2 sets of Z6's //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
i've had the boston pro's, the boston sl's, and rainbow slc's. although the pro's are beyond the latter two, i love all of them. i honestly think it's a toss up
oz me cs180's - never heard em but i want them so bad.. think they might be my next set...
my last set were memphis mclass's.. and you can get them for about half of what you want to spend.. i was very happy with them...
i got the rainbow cmx kicks.. and i love em on most songs.. but for some reason on certain songs something seems missing.. something in the upper midrange.. gonna try running em active first before i consider anything else
