Lysios - IGBTs power amp

Dionysos Lysios was the Light Aspect of the God in a complementary dyad with Dionysos Bakcheios as the Dark Aspect

lysios1Lysios is an epithet of the greek god Dionysus and it means "liberator".

Audiozen Lysios is a power amplifier conceived and projected just to let free the musical event, to allow you to enjoy it in every possible moment.

The power amplifier is the "connecting link" between the preamplifier and the loudspeakers and it mistakenly seems to be the least important part of an Hi-Fi system, just because it simply has to apply power to the terminals of the transducers.

For Audiozen it is not so. We approached to the Lysios project thinking to a different power amplifier, with great current capability but with the peculiarity of giving the perception of true realism, emphasizing the character of the upstream components. We developed the Lysios project in our laboratories and the result is a power amplifier with great dynamicness and transparency.

In addition, the IGBT is a very fast component making amazing and realistic the musical event, controlling low frequencies finely.

For Lysios we designed a quasi-complementary symmetry, polarized in AB class, with 4 IGBTs per channel manufactured by IXYS; this masterly project is enriched with a Baxandall diode, which eliminates the local Miller effect, obtaining an excellent linearity at high frequencies.

For the best listening experience the separate power supply unit is equipped with a toroidal transformer for each channel with an energy reserve provided by low ESR filter capacitors. Lysios is fully dual mono.lysios b1

All transistors are made by On Semiconductor, one of the best world company in audio semiconductors.

Audiozen is among the very few manufacturers in the world to use metal film power resistors, not the cheaper ceramic.

Lysios is equipped with binding posts that accept banana plugs, spades lugs and bare wire.

RCA connectors are made in USA by Cardas, one of the finest connectors manufacturer worldwide.

The cabinet is entirely made in aluminum..

By turning to "On" the aluminum knob located in the front panel, the professional relay, located in the separate PSU, will switch on the power amplifier.

Lysios is handcrafted in Italy choosing the best available components; our Lysios and Insight preamplifier form a pair that combines the peculiarities of tube preamp and the prerogatives of solid state output stage.
