The MOON 330A is a differential stereo power amplifier that effortlessly produces 125 watts/channel into 8Ω and 250 Watts/channel into 4Ω.
Think of tight, deep, authoritative bass with lightning fast speed, an incredibly low noise floor, excellent dynamic range, a transparent lifelike soundstage and the
330A will come to mind. This is the the result of a variety of proven technologies: Our highly acclaimed Advanced Renaissance amplifier circuit
with zero global feedback, DC-coupled circuitry and our own proprietary bipolar output transistors. In the end, the class A/AB MOON 330A performs
in an exceedingly musical and accurate way.
Our own unique heat-sink geometry allows for ultra-effective and efficient cooling. The amplifier's oversized power supply contains a large proprietary toroidal
transformer and substantial energy storage. Finally, with both balanced (XLR) and single-ended (RCA) inputs, the MOON 330A represents the ultimate
choice for performance, reliability and affordability.
