Audio Research DSi-200

Up for sale is my Audio Research DSi200 Integrated Amplifier. Purchased in 2013, the amp was used very sparingly in my home office system, and subsequently, has low hours on it. I've recently decided to downsize my audio equipment and focus on other hobbies, hence the sale.

The amp has been boxed up for the past 4 months and is ready to ship out immediately. The amp functions flawlessly, with no issues whatsoever. Cosmetically, I'm rating it a conservative 8, due to a slight smudge mark on the top of the unit near the rear vent. Audio Research had placed a small silica gel pack in the original box to reduce moisture during shipment, but unfortunately placed it in the protective bag along with the amp. During shipment, the bag slightly rubbed the aluminum top plate. It's extremely minor and difficult to see, which is why it didn't show up in my photos. There are no other blemishes that I can see. Just want to be fully transparent on the condition.
