About the 3

The Core Audio Designs Model 3 is a power amplifier designed with proprietary distortion canceling techniques to minimize amplitude-related distortions and eliminate time domain distortion by lacking overall or nested negative feedback. Each transistor is individually tested and matched for optimum operating characteristics. The amplifier maintains constant output impedance over the entire audio range, ensuring compatibility with various equipment. It uses a single voltage amplification stage with field effect transistors operating in transconductance mode to enhance low-level signal recognition. The signal path is free of capacitors, inductors, fuses, and protection circuitry to avoid their adverse effects. The amplifier features a large number of high-speed bipolar output transistors for reliability and does not require electronic protection circuitry.
