This amp is from 2011. It has about 6000 hrs on it. This isn't really much at all. It has the built in relay; so there is no blast of sound when turned on. The tubes are new and not burned in yet. It still looks quite excellent! It is a beautiful amp. With 6w of power, you can drive anything you need too. Also note that Schiit makes quite a solid product. I expect this to last years and years. Comes in original packaging! Haven't sold anything on here before. My ebay page is here: http://www.ebay.com/usr/cheezeit40 If you want proof, I can send you a message from the ebay account. Feel free to Pm me or post here if you have any questions! Trades: Feel free to Pm me. Some are very tempting, but most fall through due to international shipping costs. Preferably within the US. I am specifically interested in the O2 + Cash. I would prefer to exchange for something with cash.
