No problems Keith, always looking for ideas which is what the thread is all about, I do like the look of the SPEC amplifiers, whats the RRP on these in the UK?
This is the Korean Bakoon AMP 51 prototype,
Sorry Lee didn't mean to take your thread off course, sometimes products with a flat Fr can sound a little boring, but in time you appreciate their even handedness ,I have never been particularly fond of valves ( after a rather unfortunate introduction to the genre) and have always used fairly low powered Solid state amps with my horns, which are like your AN's pretty sensitive.
Keith.
