DPA-1 is a fully balanced pre-amplifier. The stereo operation is done by two independent non-feed-back amplifier circuit.
The exotic components assured enough bandwidth, ultra-low distortion and noise floor, even when there is no feedback applied.
Its constant impedance volume adjustment circuit is made by a network of precision resistors, which helps this pre-amp to perform exceedingly across the entire volume range.
