Descrizione

The Aleph P is a single ended Class A audio preamplifier, 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. This manual applies to the second version of the Aleph P, which incorporated circuit improvements and remote control operation. This preamplifier flows from a commitment to create the best sounding product: a simple circuit with the most natural characteristic.

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. The circuitry of the Aleph P breaks new ground in simplicity and performance. 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 singleended 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. A very few people are involved in the production of this product. I supervise all phases of the construction, and I test and listen to each preamplifier myself. If you have questions, comments, or problems, please feel free to contact me directly.

Titolo

Consonance Srl

Ricordo da bambino zia Maria a casa della nonna suonare con il Petrov Pianofortissimo di Carosone, un brano da virtuosi che lei eseguiva con naturalezza. L’idea di riprodurre la musica dal vivo in un luogo protetto come la casa di mia nonna mi ha spinto a fare di questa passione il mio lavoro. A 14 anni andai per la prima volta in un negozio di dischi, chiesi i Police e ascoltai Bring On The Night in un “Pioneer A400”: fu un momento indimenticabile, un rituale di iniziazione… Da qui è nata la mia passione: all’istituto agrario passavo ore tra i banchi di scuola ad immaginare come potesse suonare quel pezzo strappalacrime di Tracy Chapman, Baby can I hold you, con le casse di ultima generazione Yamaha. L’adolescenza l’ho passata costruendo o riparando amplificatori Marantz che trovavamo a casa di amici e parenti.A un certo punto con mio padre decidemmo di creare Consonance, per coniugare questa passione con il lavoro: e sono passati quasi 30 anni dal fatidico 21 aprile del 1991, quando aprimmo il primo negozio.
