What customers say
The Soulnote A-2 Integrated Amplifier earns high praise for its exceptional sonic performance, often surpassing much costlier equipment. Users consistently emphasize its core strengths: remarkable speed, wide dynamic range, and outstanding transparency. The nonfeedback design delivers an immediate, natural musical presentation with excellent rhythmic drive. This amplifier reveals fine musical textures without becoming harsh, maintaining a highly engaging sound. While build quality is premium, the unique top cover design is a notable characteristic. Focusing purely on amplification, the A-2 offers profound sonic value, satisfying listeners seeking uncompromising, high-fidelity performance.
Know before you buy
Non-NFB (Non-Negative Feedback) design means the amplifier does not use a feedback loop to correct errors, which helps preserve the original waveform's time-axis accuracy. This results in a more natural, dynamic, and open sound that avoids the common artifacts associated with traditional feedback circuits.
Yes, the A-2 supports BTL (Bridged Transformer-Less) monaural mode. When bridged, it delivers a powerful 400W into 8Ω, making it an excellent choice if you want to use two units for dedicated monoblock performance.
Unlike a traditional potentiometer that can degrade signal quality over time, the A-2 uses a precise relay-switching attenuator. This method uses high-quality resistors to adjust volume, ensuring the signal path remains clean and the channel balance stays perfectly accurate.
Yes, the A-2 is designed to support bi-amp configurations. This allows you to dedicate the amplifier's power more effectively to your speakers' high and low-frequency drivers for improved clarity and control.
The A-2 features a newly developed chimney-style heat sink designed to dissipate heat efficiently. While it is a powerful unit, standard rack spacing that allows for natural airflow around the chassis is sufficient for optimal operation.
The 4-layer power bus bar uses 70-micron thick copper foil to provide an extremely low-impedance power supply path. This construction ensures that the amplifier can deliver instantaneous current to the speakers, which is critical for maintaining tight bass and transient response.
