Overture PM-2i
Perfect blending of elegance and dynamics  
Musical world of pace and excitement 

A new Overture with substantial improvements

Blending the high power output of Pentode EL34, with Triode's iconic richness in musicality.
Fully unleashed the wildness and dynamic of music while having all micro details expressed with textures.
Audio Note's philosophy of an ideal integrated amplifier. A simple audio system of excellent balance. Capable of giving the best from details, dynamic and musicality.

Improvement

New design guideline "Cleaner with more Triode Splendidness" was refined through extracting the knowledge we learned from Kagura researches and applications.

Design

To develop an integrated amplifier which has best sound quality, simple and easy to use. True music lovers can enjoy various kind of music from delicate solo to big scale orchestra.

New design Push-Pull circuit

The first stage and driver stage are both direct coupling circuits. Pure silver foil capacitors are used as coupling in the output stage. Moreover, we aimed to make the entire circuit into low impedance so that transparent and direct sound is achieved. There is also a newly design circuitry CCB (constant current biasing) adopted in the output stage. It prevents music signal from flowing into the bias adjustment VR and maintain music signal's purity and integrity. Output transformer is UL connection, only 3dB NFB employed to get the best balance of low distortion and good dynamic. Furthermore, Internal wirings are skillfully arranged so that shortest paths and best performance are obtained.

Super High Quality Parts

All parts were carefully chosen after massive hours of listening tests. High grade audio volume, silver foil capacitors, silver lead resistors, SSW silk silver wires, Ls-41 shield cable, Audio Note custom made output transformers and power transformer. All CR part are carefully selected and arranged.

Big Power supply

The high reserve power supply circuit is constructed with choke coils and large capacitors group. After the ripple filter stage, the decoupling capacitors are further arranged to serve left and right channels independently. In addition, we prepared 500μF/ch in the input stages of left and right channel; achieving high headroom and wide bandwidth sound possible.
