What customers say
The AGD Solo Amplifier earns high praise for its exceptional sonic purity and speed, largely due to its innovative GaN FET technology. Users consistently report that the amplifier achieves remarkable clarity, often surpassing traditional Class D designs. A key theme is its ability to present music naturally, offering precise imaging and controlled bass without imposing a sonic signature. Many listeners find it neutral and highly resolving, avoiding the harshness sometimes found in older switching designs. Furthermore, the superb build quality reflects its premium positioning. Overall, the Solo successfully merges advanced technology with the demanding sonic expectations of discerning audiophiles, providing a musically satisfying and technically superior listening experience.
Know before you buy
GaN technology allows for significantly faster switching speeds than traditional silicon transistors. This results in exceptional transient response and near-perfect square wave reproduction, providing a cleaner, more accurate sound.
No, the glass tubes are a design aesthetic that houses the GaN power stage. They provide a classic look while protecting the advanced solid-state circuitry inside.
The amplifier is designed with a modular output stage that can be replaced or upgraded as new technology becomes available. This allows you to improve the performance of your unit without needing to replace the entire chassis.
You will need two AGD Solo units to power a standard stereo system, as each amplifier is dedicated to a single channel. This configuration provides superior channel separation and dedicated power delivery to each speaker.
The AGD Solo is optimized for a 4Ω load and delivers 500W of power. It is highly capable of driving demanding speakers, though you should ensure your speakers are compatible with its 4Ω output impedance.
No, the AGD Solo is a dedicated power amplifier. It does not include a DAC, volume control, or remote, so you will need a separate preamplifier or a source component with volume control to manage your system.
