hi everybody..i want to buy a good audio system for myslf..i currently own a Samsung Bordeax art 32",a ps3 80gb,a samsung home theatre x30(i guess),sony walkman 1gb (attachd to my ps3 via usb). i will buy a tata sky and worldspace receiver by the end of this week. My problem lies in the fact that i am very dissatisfied with these samsung speakers,n hence,i plan to upgrade. i dunt ve much knowledge about it but i surely like Logitech Z5500 speakers,the advantage being it can support 6 devices simontaneously. My budget would be somewhere around 20-40k. So guyz please help me out in making a good choice of speakers. Also mention if i need to attach an amplifier for supporting multiple devices. Thanks in advance.
