Looking for some good quality speakers and best bang for buck to connect to my MBP. Im looking at mainly the 2.1 systems. Currently I have the Logitech X240. It has a lot of buzz and noise disturbance when I put on my desk lamp or when my cell is near by there is also a lot of distortion. So my question is, whats the best speaker bang for buck, what's an attractive set of speakers and what will not have this noise problem when other electronics are on? Thanks for the help.
