where to purchase
Enormous power at an affordable price is what this amp is all about. A pure class A/B power unit, driven in parallel to deliver 450 watts/channel into 8 ohms with impeccable quality. While developing the new GFA-585se, every single part was put under the microscope to create a better & upgraded version of what is already considered a great component in the audio industry.


All circuitry meets ETL/ETLc, FCC, LVD and CE/EMC requirements using UL approved FR-4 printed circuit boards. High performance component selections include ultra low ESR electrolytic capacitors. The result is lower distortion, better dynamic range, improved damping factor and greater stability and separation of individual instruments on the sound stage.
