Ok been out of high end audio for quite a while (quite).

The Aux input is expecting a non amplified signal, the output from your computer is the output from the amplified section.

I remember issue's with certain turntables (How many of you remember them, ok most of us MBers are at least past teenie) that actually had an amplified cartridge and had to be feed into amps special.
