Bridgeable High Current Stereo Power Amp

We set out to incorporate everything we have learnt in almost 35 years to deliver a power amplifier that will set new standards and provide class leading sound quality for the best possible reproduction of your music. GFA-575se is filled with power to give impeccable voice to your speakers.

Our GFA-575se power amp demonstrates our objective to reproduce audio with a clean current, sufficient power to drive any loudspeaker comfortably and with plenty of power in reserve for dramatic dynamic swings. The GFA-575se is engineered to real-world standards, allowing your speakers - when driven by this amplifier - to perform to their maximum potential. Some amplifiers look good on paper, designed to a specification, but the GFA-575se drive real speakers, taking in stride the often difficult demands placed on an amplifier by the speaker designer.

In terms of sound quality, the GFA-575se is an exceptional performer. Its high current ability enables it to drive the toughest of loads; even the most difficult speakers are driven cleanly without the loss of dynamics. The supreme neutrality that characterizes hi-fi components shines through, coupled to effortless reserves of current to call upon whenever required, so all you hear is the music – pure and unrestrained.

Rack mounting: If rack mounted, the amplifier must be put on a shelf. Rack mounting brackets are NOT available for this amplifier.

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.
