The Momentum series amplifiers focused on combining high power output with a relatively small form factor. The Progression mono delivers extraordinary power in a larger package with the ability to drive speakers to lifelike levels. The Progression circuitry borrows greatly from the flagship Momentum to be a perfect match for virtually any speaker. The audio signal path throughout is discrete, balanced, and direct coupled. Advanced protection techniques shield the amplifier and associated components from any unexpected anomaly. Like the Momentum amplifier, the Progression circuit boards are executed with through-hole construction for the best sound quality and durability. Like all our products, the Progression series components will be built by hand in our Arizona factory.
