Need to replace my speaker system. I should say right off that my mom makes me wear phones when I play games or crank the tunes...but I need the good system when she's not home or when others want to hear what I hear. I prolly only need a 2.1 system. Thinking of the Logitech z-340. Opinions? I like to have a good handy jack for the phones (which the z-340 has, right up front). Other suggestions and why? Thanks much...
