      for a basic pre amplifier, this one is fairly good....... it seems well built, the switches/knobs work smoothly.... unbalanced input, several to choose from.... several things would make this unit a better design.... add xlr inputs and outputs, add a larger power supply, with a grounded wire to the unit, add a headphone jack in the front panel, change the color and modify the front panel design for a better sleek appearance..... it looks somewhat old-fashioned..... if the manufacturer would do that.... it would be better.............. but, for the price it is well worth it.....

      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.
