Bryston BP-3 MM Phono Stage - Silver (Requires PS3)

A Dedicated Moving-Magnet Phono Stage from Bryston

The Bryston BP-3 MM is a phono preamp in its own compact case. It takes the tiny signal from your cartridge and raises it to line level for your preamp or integrated amplifier.

It applies 41dB of gain. Bryston sets that for moving-magnet cartridges and high-output moving-coil cartridges.

Class A Circuits and Precise RIAA Equalization

The gain comes from Class A discrete operational amplifiers. Bryston pairs them with what it calls ultra-precise RIAA equalization. Distortion stays below 0.005% from 20Hz to 20kHz, and noise sits below -80dB with a 5mV input.

Powered by a Separate Bryston Supply

The BP-3 MM has no power supply inside. It runs only from a Bryston PS-3 or MPS-2 power supply. Neither is included, so plan on one when you buy.

Small Enough to Sit Beside the Turntable

The case is 5.7 inches wide, 2.75 inches high and 8.25 inches deep, and weighs 3.6 pounds. It fits close to the turntable or preamp. A front-panel switch mutes it.

How It Fits Your System

The BP-3 MM sits between your turntable and any line-level RCA input. Connections are RCA in and RCA out. Capacitive loading can be set inside the unit to suit your cartridge.

Bryston specifies it for moving-magnet and high-output moving-coil cartridges only, so a low-output moving-coil cartridge is outside its range. It has no balanced XLR connections. It will not run without a Bryston PS-3 or MPS-2 supply.

Who Is This Phono Stage Best For?

• You play records with a moving-magnet cartridge — Bryston sets the 41dB of gain for exactly that job.
• You use a high-output moving-coil cartridge — Bryston rates the BP-3 MM for these too.
• Your amplifier has no phono input — the BP-3 MM brings your turntable up to any RCA line input.
• You want to keep the phono stage near the turntable — the compact case fits on a shelf beside it.
• It is not for low-output moving-coil cartridges — and it needs a separate PS-3 or MPS-2 supply to run.

How Does It Connect to Your System?

Connect a Bryston PS-3 or MPS-2 power supply to the BP-3 MM. Plug your turntable's RCA cables into the input. Then run RCA cables from the output to a line input on your preamp or integrated amplifier.

We carry the BP-3 MM with a silver or black faceplate.
