A new Kondo Audio Note Japan Overture PM-2i integrated amplifier 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."  


The new design guideline "Cleaner with more Triode Splendidness" was refined by extracting the knowledge we learned from Kagura's researches and applications.

A new output transformer was designed for higher sound quality. By introducing the 3rd winding exclusively for NFB and re-calculated feedback amount, a good balance of dynamic and low distortion is realized.

Power and sound quality co-exist created by circuit re-design and re-tuning most CR values.

The power supply section is heavily improved and re-layout for outstanding channel separation.

Improved version of KONDO original silver foil signal capacitors for highest reliability.


To develop an integrated amplifier that has the best sound quality, simple, and easy to use. True music lovers can enjoy various kinds of music from delicate solos to big-scale orchestras.

Power tubes are famous for pentode EL34, which are the first application in the Audio Note product. To secure a minimum of 30W even matching with low-efficiency speakers. Output impedance is 4Ω and 8Ω selectable.

Reference to many classic push-pull circuits in addition to our original new ideas, the performance of the EL34 amplifier is elevated to a completely new level, combining both dynamic and delicate tonal balance.

Fulfilling the requirements of the modern specification and keep Audio Note traditional natural music performance.


The first stage and driver stage are both direct coupling circuits. Pure silver foil capacitors are used as a 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 new 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. The output transformer is a UL connection, with only 3dB NFB employed to get the best balance of low distortion and good dynamic. Furthermore, Internal wirings are skillfully arranged so that the shortest paths and best performance are obtained.


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 a power transformer. All CR parts are carefully selected and arranged.


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 the left and right channel; achieving high headroom and wide bandwidth sound possible.
