Adcom GFA7605 (Black/Silver) Open Box 125 Watt 5-Channel Power Amplifer

Now, audio playback can be better than ever before! DVD-Audio and SACD high-resolution formats provide an unprecedented level of precision to audio playback. These new formats have up to five times the frequency bandwidth of conventional CDs. The dynamic range is an incredible 144dB, which is 48dB more than conventional CD. And both formats support multi-channel playback so you can enjoy the amazing immersion that a multi-channel audio system can provide.

In the old low-resolution days, amplifier design was easier. Creating an amp was a straightforward design process using tried and true techniques that had not changed much in many years. But if you are going to design a power amplifier that can produce very high output levels and also amplify signals over a very wide frequency range, you have to move fast. To design an amplifier circuit to be fast and accurate, we needed to use a new design approach.

The heart of F.A.T. technology is our Power-Rig circuit topology which provides incredible transient response. When combined with our huge monoblock power supplies, the massive power reserves provided by the banks of power supply capacitance give you Fast Analog Transform (F.A.T.) technology. What you get is wide dynamic range and broad frequency response. The Result? Cutting-edge power amplifiers designed to maximize the performance of the newest high resolution audio formats. Listen for yourself and experience what a F.A.T. amp can do for your audio or home theater system. And remember: power never becomes obsolete.
