The Amp is about 1.5 years old and still has the 10 year warranty left. Checked out by Parasound about 6 months ago. Thought I had a problem but it was something else not related to the amp. Asking $300 plus shipping. Has some small scratches in the rear top cover, but not down to the metal. Contact either email@example.com or firstname.lastname@example.org if interested. Have original box and manual. Upgraded to a B & K amp I got halp priced.
