Jeff Rowland 555 Amplifier Silver Store demonstration unit

Jeff Rowland Model 555 Power Amplifier (Made in USA) 

American Craftsmanship. Monumental Musical Authority.

There are amplifiers that make sound… and then there are amplifiers that create gravity.

The Jeff Rowland Model 555 is a rare piece of American high-end audio history—an amplifier built not simply to drive loudspeakers, but to command them with elegance, control, and refinement. Designed and crafted in the USA, the Model 555 embodies everything Jeff Rowland is celebrated for: immaculate machining, ultra-low noise performance, and a musical presentation that feels effortless and deeply human.

This is the kind of amplifier that turns a good system into a truly serious one.

Power With Poise

Do not be fooled by its quiet confidence—this amplifier has real muscle:

• 150 watts per channel @ 8 ohms (Stereo)

• 330 watts @ 8 ohms (Mono / Bridged)

That means the Model 555 is equally at home driving refined monitors or full-range reference loudspeakers—delivering grip, speed, and scale while keeping the music flowing with a natural ease.

The signature Rowland sound is all here:
✅ Black background
✅ Explosive dynamics without hardness
✅ Beautiful harmonic texture
✅ Pinpoint imaging
✅ A soundstage that feels carved in space

Recommended Pairing: Wattson Audio Madison DAC

At Sunny’s, we have found a truly magical synergy when the Model 555 is paired with the Wattson Audio Madison DAC. The Madison brings purity, tone, and timing; the Rowland provides the authority and resolution to unlock everything the DAC is capable of.

Together, it’s the kind of pairing that surprises even seasoned audiophiles—high resolution without fatigue, powerful yet graceful.
