Sometime in April 2024, I have received a request from someone who has a special requirement for his system. He wanted a preamp to connect two stereo amps to bi-amp his speakers with ability to adjust top and bottom individually. Plus, connect his digital recorder and headphone amp all in one preamp. The result is this custom preamp.
