Dan D’Agostino Momentum Preamplifier 2 Channel

2 Channel Stereo Preamplifier

MSRP $35,000.00

Only the Momentum preamplifier can deliver the sound quality necessary to get the maximum possible performance from the Momentum monoblock and stereo amps.

Like the Momentum amplifiers, the preamplifier uses complementary balanced circuit topology for maximum bandwidth and low noise. Its audio circuitry is fully discrete, with no op amps. Zero-feedback design assures the most musical sound quality. Volume adjustment is made through a resistor ladder governed by an optical controller—the cleanest, most transparent possible method of controlling volume.

We have the Silver Preamp on our Showroom floor.

A 300 VA power supply in a separate chassis isolates the preamp’s sensitive circuitry from electromagnetic interference and noise.

Separate supplies power audio and control circuitry, so the control circuits are completely isolated from the audio circuits.

The styling of the Momentum preamp perfectly complements the Momentum amplifiers, with copper accents to match the amplifiers’ unique copper heat sinks. The meter on the front face of the preamp indicates the volume setting, and a ring around the meter controls the volume. The front selector buttons illuminate to show which input is active. A radio-frequency (RF) remote control that works through walls is included.

Just like the Momentum amplifiers, the preamp uses through-hole construction and is hand-built and individually tested in D’Agostino’s Arizona facility.
