Audiophile circuit design
This preamplifier has a circuit designed for fully balanced applications. Thus the inputs, the volume control, the preamplification stage are all fully balanced with no conversion stage at all.
It uses two high-performance stereo LME49860 operational-amplifiers mounted on DIP-8 support (removable). The latter can then be renewed / changed in order to adapt the overall sound signature. The amplification stage is hybrid, that is to say it relies on OPA as well as discrete components subcircuits.
The output stages are constructed from discrete components with differential signaling architecture, which ensures excellent stability in output signal.
