hi there, just trying to get some advice from those Mac users with some audio expertise and experience. i need to buy some speakers. am i better off with two book shelf speakers or a complete 2.1 system (satellites and a most likely horrible subwoofer)? budget is basically ~$300. i've found this pair of Klipsch bookshelf speakers that i'm really liking, although i don't really know what to look for in regards to specs on speakers. i've been comparing that pair with this 2.1 Klipsch system. which is the better choice? i'm also considering a USB amp or something like it to bypass the average soundcard in my MBP. i have a feeling the best setup would be a USB amp + the bookshelf pair but i want other opinions before i buy anything. typical needs are focused on music with the ability for loud crisp sounding output when necessary. i listen to all types of music in case that matters.
