I'm thinking about changing speakers on my iMac. I'm currently using the HK Soundsticks II. They look great and sound good. But what I'm thinking is something more. I have an extra set of Klipsch 2.1's which might just sound better but they're kinda blah looking. Then I remembered there are some speakers (Bose Companion 5's) which are connected via USB. If I'm correct you can change the volume by the remote(nob) or the keyboard buttons. That way there is none of the volume up all the way on speakers and then control by the keyboard or vice versa. This has alway bugged me as the occasional blast of sound happens when you forget what was last done on the computer. So I'm trying to find either great speakers or suggestions with USB controlled stuff to avoid the situation with normal headphone jack speakers.
