Dan D'Agostino Momentum S250 MxV Two-Channel Amplifier

The Momentum S250 MxV stereo amplifier delivers the extraordinary sound quality of the Momentum M400 MxV monoblock in a more affordable stereo design. The circuit topology and construction of the stereo amplifier mirror those of the monoblock, using the same ultra-efficient copper heat sinks with venturi cooling, the same 1% metal-film resistors, the same 69 MHz output transistors and the same fully complementary balanced configuration. The result is audio fidelity equaled by no other amplifier—except, of course, the Momentum M400 MxV monoblock itself. The leading compliment to the Momentum S250 MxV Stereo is the Momentum HD Preamplifier, creating a harmony worthy of any aficionado.

The Momentum S250 MxV models feature techniques and topologies initially developed and implemented in the Relentless Mono Amplifier. This fullest expression of the Momentum circuitry is reflected in the new model name, MxV. Those with a physics background will recognize that MxV or Mass times Velocity is the equation for Momentum.
