Is there a way to hook up a Mac desktop, laptop and/or IPOD to bookshelf size speakers (these are high end) and even surround mini speakers? These speakers do not have their own amp built in. I am not technical enough to know how to do this without help. I want to get a new Mac for my girlfrined and I found these very cool bookshelf size speakers I wanted to hook the mac up to for incredible sound. What do I need to do to make this happen? Do I need an amp as well? Do I need special cables? The main speakers have the following specs 2 Ways Bassreflex, Not shielded Recommended amp 20-75 watts Peak Power 150 Watts Impedance 4 Ohms Efficiency 88db Frequency Response 70Hz - 20 Khz Thanks for the help.
