Proton AA1150 Stereo Power Amplifier * Fully Serviced * Rare !
The Proton AA-1150 is a well-regarded vintage solid-state power amplifier, praised by audiophiles for its surprisingly robust power delivery (thanks to its clever Dynamic Power Delivery or DPD circuit, similar to NAD's designs), low noise floor, and ability to handle tough speaker loads, often exceeding its modest wattage rating for dynamic peaks, offering clean, detailed, and powerful sound that punches above its weight in the vintage audio world
