Soulnote A-2 Ver 2 Integrated Amplifier

Soulnote A-2 Ver2 Integrated Amplifier Key Features: 

Parallel Push-pull Output Stage

The output stage features a parallel push-pull configuration with the same high-speed, high-power TO3P transistors used in the A-3.

Precise Pairing of Transistors

Each transistor is precisely paired by hFE, eliminating the tonal smearing typically associated with parallel push-pull designs.

Reinforced Driver Stage with TO3P Transistors

The driver stage also employs TO3P transistors identical to those in the output stage. By maintaining a high standing current in the drivers, hFE fluctuations caused by current changes in the output stage are instantly compensated, delivering exceptionally strong drive capability. This marks the key difference from the original model and represents a technological breakthrough.

Refined Voltage Amplification

A newly developed voltage amplification circuit, created specifically for the A-2 VER2, significantly simplifies the circuit and introduces a completely re-engineered bias circuit for improved stability and performance.

High-Capacity Power Supply

A large, unimpregnated toroidal power transformer has been adopted. By lowering the output voltage compared with the original, the A-2 VER2 prioritizes instantaneous current supply capability at low impedances over maximum output at 8 Ω, ensuring dynamic and responsive performance.

Relay-based resistance switching volume circuit has been employed as the same as the original. 

Unfixed Structure

Increased clearance of the unfixed top cover allows for a more open feel. Other features incorporate the know-how of the 3 series in the chassis structure. (E-2 VER2 and D-2 VER2 are also the same.)
