Pass Aleph P Single Ended Class A Pre-amp in pristine condition.
This preamp is cosmetically and functionally in excellent condition. I couldnt find any marks on this. Always kept in a dedicated rack connected with Aleph monoblocks.
he Aleph P is a single ended Class A audio pre-amplifier, the first produced by Pass Laboratories. It combines completely new design thought applied to a traditional topology and the experience of twenty five years of amplifier design. The Aleph P integrates power Mosfet devices and single ended Class A operation in a simple topology in order to deliver the most natural sound possible. Each gain stage consists of a single Mosfet power transistor operated “common source” mode. One such circuit amplifies each signal polarity of a balanced input signal, and their operation is inter-coupled to allow optimal operation with both balanced and unbalanced input signals while still providing balanced and unbalanced outputs.
It retains the important simple single ended characteristic while operating either single-ended or balanced.
It is unique in providing superior flexibility and performance with balanced and unbalanced inputs and outputs, converting one to the other as desired without switches or adapters. The Aleph P absolutely minimizes the number of components in the signal path, and yet retains exemplary objective performance specifications.
More importantly, it pushes the edge of the art in exploring how much subjective quality is obtainable with a new but very elementary gain stage.
