I received this serviced unit about three months ago and used it until recently. It delivers superb sound with depth and warmth, from low to high power-sound that can only be experienced with a vacuum tube amplifier. I have been listening to CDs and records through vintage 8-ohm Mitsubishi Diatone speakers. It produces a wonderful, timeless tone that never becomes tiring. It is completely different from a transistor amplifier-this is the quality you expect from a vacuum tube amplifier. If it does not produce sound properly, I will address the issue.

THANK YOU FOR LOOKING.
