Hifi system
 

Hi
I'm planning to buy a good hifi system. It should be 2+1 (stereo speakers + subwoofer). It should have very good audio quality, as Sennheiser px100-II or Genius SP-HF1800A. I can't pay more than 150-200$. It should compromise semi-pro audio quality and good price. It should be not very large. It should have cd player, usb and mini jack input and fm radio. ()
What would you advise to buy?
Thanks in advance
Martin
