Momentum Phonostage

Incredible flexibility and EQ from the finest analog circuitry with the precision of digital control

Uncover Hidden Depth and Soul

Locked inside those record grooves is the most realistic and natural sound one could ever experience. The Momentum Phonostage extracts every last bit of music hidden in this microscopic landscape. Combining the finest possible analog circuitry with the precision of digital control, this phonostage offers vinyl lovers unmatched flexibility and unrivaled reproduction of audio’s most enduring recorded medium.

Advanced Materials and Confident, Uncluttered Design

Front panel pushbuttons control gain, loading for MC and MM cartridges and record EQ curves. The AC power supply may be the cleanest ever created for a phono preamp, with enough inputs to handle multiple tonearms and turntables. Meanwhile, uncompromising parts selection and advanced construction ensure performance that is the equal of every other component in the Momentum Series.

The Most Delicate Signal

The challenge of preserving the most delicate low-level audio signal generated by the phono cartridge, as it makes its way to the phono preamplifier, and through the pre- and power amplification stages to the loudspeakers is a daunting one. The Momentum Phonostage is the result of tackling the pursuit of what seemed like the unattainable in a phono preamplifier. With the Momentum Phonostage, every last bit of microscopic musical information on the finest vinyl records is preserved intact. Paired with the Momentum C2 Preamplifier and the Momentum MxV Series amplifiers leaves only wonder and awe.

Incredible Flexibility and EQ

The Momentum Phonostage combines the finest possible analog circuitry with the precision of digital control. Every adjustment can be made from the front panel, each with its own LED readout. Pushbuttons on the front panel precisely control gain, resistive loading for the two MC inputs, resistive and capacitive loading for the two MM inputs. Importantly, the user has the ability to fi ne-tune record playback through the selection of a variety of record EQ curves used by recording studios from the beginning of phonography.

The Momentum Phonostage features four inputs to accommodate multiple tonearms and turntables. It has two moving-coil inputs and two moving-magnet inputs, each with XLR and RCA jacks, plus XLR and RCA outputs.

Power, Pure and Not So Simple

Knowing that even the best circuitry is no better than the electricity that powers it, the Momentum Phonostage uses a special AC power supply. Not one but two separate power supply components: a transformer that sits on the floor, and power rectification and regulation circuits built into the base on which the Phonostage sits. Thus, the sensitive phono preamp circuits are double-isolated from the transformer electrically, and also separated by a safe physical distance.

The Momentum Phonostage was born without limitations to support the most dedicated listeners with substantial record collections.
