This is a Cambridge 841a v2 Integrated Amp. It is in perfect condition. There is not a scratch on it. I have used it about 40-50 hours and I have an opportunity to move up to separates. It has a wonderfully smooth sound. I have used it with Snells and with Klipsch RF-83's and Chorus and it sings. Here's a link to get the info. I apologize in advance for the poor photography. But I can promise you the amp is awesome.
