You have the perfect amplifier. Buy it does not do anything you can see. Your buddy has one of those amplifiers with the big blue meters. You just love watching those needles fluctuate back and forth. If only you could get that.
Now you can keep your and have meters.

Yes, this will save me from an expensive Macintosh, Technics or Yamaha impulse purchase.
