Keny,
I assume you can only buy one or the other at one time and perhaps can't audition them in advance. There is absolutely no way you can tell which you will like better without hearing them in your system. If you go with one, in the back of your head, you will probably keep wondering what the other sounded like. I can only tell you that MAC gear will mate very nicely with either one it's just a matter of what you like. I vote to buy one brand here used, live with it for a few months, sell it here, and then try the other brand again buying here used. If you like the first pair better, sell the second and buy another pair of the first again or if you like the second pair better, just keep it. I guarantee whichever you decide to keep, that won't be your last pair of speakers. The worst it will cost you is shipping as you won't lose money on either pair being them here used. Keep in mind that this hobby is a continual journey that will last a lifetime, so that you don't need to be in a hurry to find the "perfect" match, the fun part of this hobby is the journey. Good luck,
Mike.
