Don't let the small size fool you.

The Opus 21 system from Resolution Audio introduces a new level of performance and convenience, delivering audiophile performance without devouring your home or emptying your wallet. In a market of ever-increasing bulk and complexity, the Opus 21 family offers a fresh departure with elegance that is at home in any environment.

Available in a variety of configurations and color combinations, the Opus 21 can start as a simple cd player and evolve to a complete two-channel system. No analog interconnects are required, and only a single cord powers the entire system.

The Opus 21 frees you to focus on the music, not the equipment.
Conservatively rated at 80 Watts/ch, this dual-mono compact powerhouse perfectly completes the Opus 21 system.

By marrying the unique UcD output modulator to a refined power supply and precision-tuned front-end, this amplifier delivers audiophile performance that is the hallmark of the Opus 21 family.

Choose the s30 for high-efficiency speakers, or the new s80 for conventional speakers.
