Pro-Ject AMP Box RS Stereo Power Amplifier

Amp Box RS

Highend Stereo Power Amplifier

Ultimate high-end sound quality paired with compact dimensions and high energy efficiency

Four special features distinguish this high-end power amplifier:

• 1. complex double mono construction
• 2. highly efficient and energy-saving PWM amplifier modules
• 3. tube buffer preliminary stage
• 4. can be upgraded with linear power supply for more power and even better sound quality. The optionally available linear power supply PS Box RS makes this reference amplifier a high-end dream.

Together with Pro-Ject Pre Box RS you get the ultimate dream combination that will delight every audiophile listener!

The combination of spatiality, fine dynamics and resolution, large power reserves and 2 ohm stability make the Amp Box RS a cost-effective reference that is also perfectly suited for bi or tri-amping applications.

Not suitable for use with Design Box Acrylic due to heat generation.

The brushed aluminium front is available in silver or black.
