DNA-0.5

About the DNA-0.5

The McCormack DNA-0.5 is a stereo power amplifier known for its high output and reliability, featuring a protection circuit to safeguard the unit. It delivers 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, both channels driven from 20 Hz to 20 kHz at less than 1% total harmonic distortion (THD). The amplifier employs the Distributed Node Amplifier (DNA) design, which places smaller capacitors directly beside each output device for faster, cleaner music reproduction. It has a frequency response from 5 Hz to 200 kHz, total harmonic distortion of 0.05%, gain of 30 dB, input sensitivity of 0.85 V, and a signal-to-noise ratio of 100 dB. The unit measures 19 x 5-7/8 x 15 inches and weighs approximately 30 lbs. It features a robust build with exposed heat sinks for ventilation and a massive E-core transformer shielded to prevent EMI. The amplifier is well-regarded for its sound quality and engineering, with some units upgraded to a Gold+ Edition by Steve McCormack, enhancing components such as the transformer, internal wiring, and connectors. The DNA-0.5 remains a sought-after amplifier for high-fidelity stereo setups.
