I recently bought a pair of M-Audio Bx5a Studio Monitors used from my local Music Go Round. I was nervous about buying monitors used for obvious reasons but i have to say that they are quite good. I like them a lot more than my old KRK Rokit 6's. The Bx5a's have a much clearer sound and have a flatter response. I highly recommend these monitors. They were very easy to set up. I am using balanced TRS cables to connect it to my mixer.
