I wanted a small amp for a bookshelf set up. I also wanted valves. This fitted the bill and from the moment I received it I've been happy. Very good looking, very good build quality and a sound quality I really like. It controls my Celestion SL12Si's driven in bi-amp mode by 2 Linn power amps so that's streets away from being used as a headphone amp. It's a real pre-amp and the valves are easily available.
