Manufacturer description

ADCOM's dedication to uncompromising sonic reproduction, innovative circuit design, and the highest quality electronic parts guarantee that, dollar for dollar, you're getting the best value in the audio world. At 300 watts per channel into 8 ohms and 450 watts per channel into 4 ohms, the GFA-5802 combines innovative all MOSFET circuitry with a tremendous power supply to outperform any amplifier, even those selling for two to three times the price. To produce this remarkable amplifier, ADCOM started with an enormous toroidal power transformer. Totally separate secondary windings and independent ground connections ensure each channel is completely isolated from crosstalk and AC line interference. Lots of clean power for lots of clear and powerful sound. Even the neighbors will enjoy it. In addition to the GFA-5802's main toroidal transformer, a separate front end transformer is also used. This additional device isolates the front end input stages from the main output section so any peak demands from the output stages will not decrease the operating voltages for the input sections. This design also contributes to improved separation at the inputs for precise sound staging and imaging. ADCOM's GFA-5802 power amplifier also has exceptionally large capacitors to store large amounts of reserve current for supply to the speakers. This large storage capacity means that the amplifier won't be starved for power when you're driving low impedance and/or inefficient speaker systems. Now your speakers and your music can sound the way you expect them to. All the time. The well organized and simple design of the GFA-5802's glass epoxy circuit boards ensures outstanding and reliable operation. Using only single ended Class "A" circuitry in the front end, the ADCOM GFA-5802 delivers the pure sound that other amplifiers can only talk about. All devices are precision matched for maximum performance, negligible distortion, and higher output currents. The GFA-5802 comes with versatile binding posts for easy speaker hook up. Accepting either standard stripped or "tinned" wires, single or dual banana plugs or spade lug connectors, the GFA-5802 is a great match for any system. And since it can drive virtually any speaker system regardless of its impedance, even the most demanding speakers will sing beautiful music. Additionally, the GFA-5802 also comes equipped with two sets of binding posts for each channel. These extra binding posts allow the GFA-5802 to accommodate speaker systems that have "bi-wire" compatibility. ADCOM makes sure that the sound created by your other components can be flawlessly transferred to the GFA-5802's balanced power and optimum circuit technology. The GFA-5802 is equipped with two types of input connectors for complete compatibility, high quality gold-plated RCA jacks and XLR jacks. The GFA-5802's professional grade three pin XLR jacks provide positive, negative, and shield connections. The result is a balanced line connection between the GFA-5802 and your other balanced line components. This connection is essentially immune to electromagnetic and radio frequency interference and provides a significant reduction in common mode noise. Through a combination of dependable technology, innovative engineering techniques, and efficient use of the highest quality parts the ADCOM GFA-5802 is quite possibly the best amplifier you may ever hear. It is one of the most sought after audiophile products in recent years. From its toroidal transformer and giant capacitors to its reference grade HEXFET circuitry, the ADCOM GFA-5802 is built to be the best amplifier money can buy. After you hear the GFA-5802 you'll agree that it's an incredible value in high-end audio. Your ears will thank you. And so will what's between them.
