hello! i've been producing electronic music as a hobby for some time now, but i never had monitors so now i'm thinking about buying a pair. since i do not have much to spend i think the behringer truth 3031a would be a good decision (about 360€). i know that they are not the best, and i know many people don't like behringer products, but from what i've read on the internet until know, the truth 3031a seem to be a good deal for the money... i've not had the chance to hear them until now, so does anyone from you know them and can tell me something about them? do you like them or are they really not good? my second question: if i get new moniors, which is the best way to connect them to my macbook pro? i thought i could buy an adapter and connect them directly to the audio out of my laptop, but some people now told me i should better invest more money and buy an audio interface... is that really necessary? i do only produce internally with logic, i don't record something... what would be the advantages with an interface? would the sound be better? if it's really necessary, which one should i buy? i'd like to have a firewire interface, but there are not as much out there, so usb would be okay too! i thought about something at the price of the m-audio fast track pro for example! thank you very much!
