The A-0 ver.2 is a distinctive integrated amplifier from Soulnote, built with a wide bandwidth and an exceptional signal-to-noise figure despite a modest power output. The A-0 ver.2 brings Soulnote's uncompromising engineering to a substantial integrated chassis.
Key specs that matter
Two balanced XLR inputs and two single-ended inputs are provided. Input impedance is 50,000 ohms balanced or 25,000 ohms single-ended. Output power is a modest 2 x 10W into 8 ohms - a deliberately restrained figure reflecting Soulnote's distinctive engineering philosophy prioritising sonic purity. Gain is 22dBu. Frequency response spans an exceptionally wide 5Hz to 350,000Hz within plus-or-minus 3dB - a remarkable range far exceeding typical integrated amplifier specifications. Signal-to-noise ratio is an exceptional 115dB. At 430 x 109 x 418mm and 8.0kg, the A-0 ver.2 maintains a manageable integrated amplifier chassis reflecting Soulnote's uncompromising engineering standards.
Sound and use context
Expect exceptionally clean, distinctively engineered amplification reflecting the exceptional 115dB signal-to-noise figure combined with the exceptionally wide 5Hz-350kHz bandwidth, with the modest 10W-per-channel output best suited to notably efficient loudspeakers.
Pairing
The modest 10W-per-channel output pairs best with notably efficient loudspeakers to achieve satisfying dynamic headroom.
Alternatives
Soulnote's own A-1 offers a considerably more powerful alternative within the same broader integrated amplifier catalogue.
