      Quality:

      This unit produces excellent sound quality.Tone controls work nicely.Variable loudnessis a plus. I don't care for the stepped volume control because it limitsyour ability to get the volume exactly where you want it. I would like to see an update of this unit with a switched power outlet for a power amp.
