About the 1B-MC

The Bryston 1B-MC is a highly regarded solid-state preamplifier featuring an integrated moving coil (MC) phono stage, designed for audiophiles seeking exceptional analog resolution and soundstage. It offers a frequency response of 20 Hz to 20 kHz with ±0.1 dB accuracy, extremely low distortion (0.005% IM or THD), and a maximum output of 10 V rms (typically up to 20 V rms available). The unit includes master volume and balance controls, a low-frequency filter active below 31.7 Hz, and mono/stereo operation selection. Input sensitivity for phono is approximately 0.8 mV at 1 kHz, with very low noise levels (phono rated noise at -80 dB A-weighted). The 1B-MC was produced with options for moving magnet (MM) and moving coil (MC) inputs, with some units specifically configured for MC cartridges. It is known for its warm, musical sound and large soundstage, though some users note that dedicated modern phono stages may offer more resolution. The 1B-MC is considered one of Bryston's most overbuilt and durable audio products, maintaining a strong reputation among vintage and high-end audio enthusiasts.
