Great purchase,premium look and premium sound,pre-amp built-in,really easy to set up,and rca,optical,speaker wire,and usb-sound cables included as well,over all a great product,the knly flaw (In my case)I have the speakers on my desk and can't get the back right speaker very close to the wall due to the power chord,but thats just me,Would've love a flat-to-body of the speaker power cable on the back,
