A-0 Ver. 2 Integrated Amplifier

Premium Silver / Premium Black

3 Series - Based on the knowledge gained from the series, the dramatically evolved version 2

Fully non-feedback discrete circuit

A fully discrete, fully non-feedback circuit is used throughout. The extremely simple configuration, consisting of a power amplifier with a selector and volume, is exactly the same as that of flagship models such as the A-3.

Single push-pull output stage with TO-220 transistors

The output stage uses TO-220 type transistors in a single push-pull configuration, which have low CoB and excellent high-frequency characteristics. This is a high-end amplifier that is fully focused on quality, which can only be achieved by limiting the maximum output to 10W.

4-stage Darlington circuit

Despite its maximum output of 10W, it uses the same 4-stage Darlington configuration as its higher-end model, delivering astonishing driving power that makes you feel the change in air pressure even at low volume levels.

Newly developed bias circuit

A newly developed bias circuit replaces the conventional LED bias circuit, dramatically improving signal-to-noise ratio.

Enhanced pre-out function

- For pre-out output, you can now select a powerful High mode that outputs the speaker output as is, or a user-friendly Low mode (same as the original A-0) where the output is attenuated.

- A mode has been added that outputs speaker output when a preamp is selected. A mode that stops speaker output (same as the original A-0) can also be selected.

- In addition to RCA terminals, the pre-out terminals are also equipped with XLR terminals. The XLR terminals have ① GND, ② Hot, and ③ Floating GND, allowing you to expect the noise cancellation effect that is a benefit of balanced connections. By using our non-shielded balanced cables such as the SBC-1 or RBC-1, you can maximize the power of the unit as a preamplifier.Non-fixed TOP cover.

Non-fixed TOP cover

By leaving the top cover unfixed, we have achieved a natural sound field and a sense of openness.

Direct Mechanical Earth Construction

By placing the feet directly under the transformer, harmful transformer vibrations are released directly outside the chassis. In addition, by supporting the product's feet at three points with spike pins, muddy sound caused by chassis damping is eliminated, resulting in a lively, soulful sound.
