"Yep, organ, horns, acoustic guitar. Most everything. You may have heard this before, but, I am hearing things I have never really heard on most anything I play on fairly low volume . I don’t need to push it for it to sound sweet ! Flagship really makes it. I have not gotten the sound I hoped from the Cornwalls until now. I’ve had them since 1986. I think I’ll keep them."

A meticulously engineered 10W solid-state amplifier built around pure Class A operation and a fully discrete, hand-wired signal path. Designed for linearity, stability, and musical transparency, this amplifier delivers consistent performance without the complexity of feedback-heavy designs.
At its foundation is a robust single-transformer dual power supply architecture, utilizing independent secondary outputs, dual rectification stages, and separate capacitor banks. This approach provides channel isolation, ultra low noise, and excellent current delivery.
The output stage operates in continuous Class A bias, ensuring zero crossover distortion and maintaining a smooth, highly resolved presentation across the entire frequency range.
