Stereomour II

About the Stereomour II

The Bottlehead Stereomour II is a high-quality single-ended, parallel feed, directly heated triode (DHT) stereo integrated amplifier kit. It uses 2A3 output tubes to deliver approximately 3.5 watts per channel, offering a great sense of realism and linearity typical of DHT amplifiers. The amplifier features a driver stage regulated by a Camille Cascode Constant Current Source (C4S) for low noise and high gain, with an optional shunt regulator upgrade kit that adds shunt voltage regulation to improve bandwidth and dynamic performance. The Stereomour II supports three inputs and can be configured for either 2A3 tubes (3.5Wpc) or 45 tubes (1.75Wpc) with user-supplied tubes. It is compact compared to other Bottlehead amplifier combos like the BeePre/Kaiju, making it suitable for setups where space is limited. The amp is well-suited for efficient speakers such as horn or open baffle designs and is appreciated for its clear, balanced sound with a focus on midrange and highs, though some users note the bass response is less extended compared to other models. The kit includes the 2A3 tubes and parts for both tube configurations, with the shunt regulator upgrade available separately. The amplifier is designed for audiophiles who value the musical qualities of directly heated triode amplification and DIY assembly.
