Know before you buy
Class-A mode provides the most refined, tube-like warmth and sonic texture, though it consumes significantly more power and generates more heat. Class-AB mode is more energy-efficient and practical for casual listening while maintaining high fidelity.
Yes, the SA-Reference is bridgeable and can be converted to mono operation. In this mode, it delivers a substantial 1,000 watts into 8 ohms, making it suitable for driving demanding, power-hungry speakers.
Yes. Because the amplifier features massive heat sinks and draws 1,100 watts in Class-A mode, it requires significant open space around the unit to dissipate heat effectively. It should not be placed in an enclosed cabinet.
Yes, the unit is equipped with both XLR inputs for balanced connections and RCA inputs for unbalanced connections, ensuring compatibility with a wide range of high-end preamplifiers.
The SA-Reference weighs 125 pounds, so you will need a very sturdy, dedicated equipment stand or floor space. It is not rack-mountable and requires a stable, level surface to support its substantial mass.
No, the SA-Reference is a dedicated power amplifier and does not include a digital-to-analog converter or a remote control. It is designed to focus purely on amplification, requiring a separate preamplifier to manage volume and source selection.
