Hello Bob,
I completed a Bottlehead Foreplay III about a month ago and run it with a Perreaux power amp. It is a HUGE improvement over the Perreaux 2A Class 1 pre-amp that I was using. It is not perfect for low output moving magnet cartridge (Grado .5 mv) because you have to turn the gain up really high and use a phono stage, but for a higher output device, like cd player or higher output turntable cartridge, it is really good. Also, it's a lot of fun to build. The instruction manual is very complete and the folks at Bottlehead are really easy to deal with.
