I purchased this amp after reading many positive reviews online. The AudioSource AMP-100 amp lives up to all of them. This amp sounds gives a very clean, natural, tight sound. For just over $100, this is easily the best quality budget amp around. The case is an attractive solid black case with binding post connections. Something rarely seen at this price point! I am now using this amp to replace a much more expensive tube hybrid amp that has given me problems since day one. I plan to order another to power another set of bookshelves in the same system. If you're thinking about buying this amp, go for it. You won't be disappointed.
