Ajax, thanks a lot for your response... I couldn't really tell if it's my speaKers or the amplifier creating the distortion that I was hearing. I just replaced my speaker cables with the Cobalt "Ultimate speaker cables" and I'm not sure if the cable helped at all. I can still hear the highs as if it was distorted.
