Eden Microphone Preamplifier

This is the Eden Microphone Preamplifier from Expat Audio. It comes are a completed module that only needs to be hooked up. In fact, all it needs is power, input, output and a gain setting resistor. It's assembled and tested here in Texas, USA. Performance It has flat THD+N at 30dB of gain as low as 0.003%, all the way to 30kHz (higher I believe - but the audio test kit isn't quite up to it). At 60dB of gain (max setting) the THD+N is still very impressive at 0.04%. (again, flat all the way!)    What's in the box? A single Eden board made and tested in Dallas, TX. What else do I need to buy? To make a complete mic pre system: Power Supply, Front End, Case, Pot and Switches.
