The Euphono is the Audiozen Reference tube phono preamplifier for MC (Moving Coil) and MM (Moving Magnet) cartridge; Euphono is equipped with three NOS tubes and two FETs to ensure the best performances with both types of cartridges.


Euphono includes the minimalism of Audiozen philosophy along with sophisticated circuit solutions: the input tube, an ECC81 (12AT7), polarized with a "cascode" circuit developed by Audiozen, directly amplifies the signal of MM cartridge or, by a FET placed on its cathode, brilliantly manages the low output of an MC cartridge.


The FET, compared to an additional tube, ensures lower noise and a very high input impedance: this configuration don't alter the small audio signal and, furthermore, cancels the Miller effect, which would be detrimental to the frequency response; this ensures that it is always the tube to pre-amplify, the FET just"helps" the tube in its work.


The FETs for the two channels are "matched", so they have identical electrical characteristics.

The excellent passive RIAA network, calculated according to the Audio Engineering Society parameters, it's the result of theoretical calculations and laboratory tests: it exceeds the specifications at all frequencies.


The elegant aluminum knob located on the front panel of the unit acts the MC / MM cartridge type selector.

The Euphono is equipped with a separate power supply unit which includes two toroidal transformers, the first is used for the tube filaments supply, the second, connected in series to have a complete galvanic separation, generates the anodic voltage: this configuration can be used when the needed current is not high and it has the advantage of drastically reducing the ripple.


The Euphono is equipped with ClarityCap SA series fine polypropylene capacitors in the audio signal path.

All these features made the Euphono the definitive MC/MM phono preamplifier even for the more demanding audio enthusiasts.
