The BP-2 MM is a compact phono preamplifier from Bryston, built specifically for moving-magnet cartridges without moving-coil switching. Bryston built this straightforward MM-only design as a simpler, more affordable alternative to the brand's switchable MM/MC phono stage, aimed at buyers whose system uses moving-magnet cartridges exclusively.
Position in line
It sits below the BP-2 MM/MC in Bryston's phono stage range, the simpler of the two variants with MM-only gain rather than switchable cartridge types. This deliberate simplification suggests Bryston recognised many buyers do not need moving-coil compatibility and offers this more focused, likely more affordable, alternative specifically for them.
Key specs that matter
Gain is 41 dB, standard for moving-magnet cartridges. Distortion is under 0.005%. At 57 x 27.5 x 82.5 mm and 1.6 kg it is a compact unit, small enough to tuck discreetly out of sight near the turntable.
Sound and use context
Expect a clean, low-distortion presentation typical of a well-executed solid-state MM phono stage, without the added complexity of moving-coil switching - a focused, no-frills solution for a straightforward moving-magnet vinyl setup.
Pairing
This unit works only with moving-magnet cartridges - a moving-coil cartridge needs the MM/MC variant or a separate step-up device, a firm limitation worth confirming against the specific cartridge already owned before purchase.
Alternatives
The BP-2 MM/MC sits above this model with switchable gain for both cartridge types, for a system that may use a moving-coil cartridge at some point, worth the modest premium if cartridge flexibility matters for future upgrades. Bryston famously generous warranty terms extend across its electronics catalogue, worth confirming specifically covers this phono stage before purchase. A dedicated ground connection between turntable and phono stage remains essential for hum-free operation regardless of which specific unit is chosen. Buyers should also verify the specific cartridge output level falls comfortably within this unit fixed 41 dB gain range before assuming compatibility, since a mismatch would leave playback either too quiet or prone to overload. Overall this remains a sensible, focused choice for a straightforward moving-magnet vinyl setup. A short, well-shielded interconnect between turntable and this unit also helps minimise any risk of noise pickup.
