About the Premier 8A
The Conrad Johnson Premier 8A is a high-end stereo tube power amplifier known for its clear, consistent quality and large, layered soundstage. It delivers 275 watts RMS from 30Hz to 15kHz at no more than 1% total harmonic distortion (THD) or intermodulation distortion (IMD) into 4 ohms, and can be connected for 2, 8, or 16 ohm loads. The amplifier features a frequency response of 20Hz to 20kHz within ±0.1 dB, an input impedance of 100 kOhms, and a hum and noise level 96 dB below rated power. It uses sixteen JJ Electronics 6550 output tubes, eight GE 6CG7 tubes, and four JAN 5751 tubes, housed in tube cages. The amplifier measures 19 inches wide, 9.5 inches high, and 21 inches deep, weighing approximately 90 lbs. Audiophiles praise its ability to reveal musical nuances, with rich harmonics, realistic transient attacks, and a spacious soundstage. The Premier 8A is regarded as a faultless design with excellent factory support and a visually appealing champagne tone metal finish with glowing tubes.
