Manley Stingray iTube Stereo Integrated Amplifier



EveAnna Manley is a very interesting personality. She is great fun to talk to, and she knows as much about tube circuit design as anyone I have ever met. I have never asked her a question about circuit design that she couldn't answer.

Her hi-fi products are just as unique. They are all named after fish, in the current case, the Stingray, which has been around in her arsenal for a while. But, the latest version is even more unique. It has an iPod dock right on the front. When you put your iPod in the dock, it blocks your view of those warm and cuddly little tubes, but so be it.
