Audio Help

[mr1 sniper]

I am looking to replace my current shelf stereo system I have in my room and am looking for one with good sound but I am also obsessed with bass. Could anyone tell me if they have had any experience (good or bad) with these three or suggest a different one. I will be using an iPod so the dock is nice but sound is more important. With the jvc i can find it for the same price as the sony. Thanks
