Simaudio MOON 888 Power Amplifier

Top-of-the-line power amplifier for the demanding audiophile.

The MOON 888 is not merely a monoblock amplifier, but an uncompromising executor of sound. If the goal is sound that disappears, leaving only the music – this device is for that. You can trust that your speakers will receive power, control, and purity rarely found in one package.

Ultimate Power – Without Compromise

The MOON 888 is designed to drive even the most demanding speakers without altering the purity of the signal. In a single-channel (monoblock) configuration, it delivers an impressive 888 watts into 8 ohms, offering absolute stability even with high current outputs. MDCA topology eliminates global feedback, ensuring exceptional dynamic integrity and phase accuracy. Every detail is designed to serve the music – instantaneous power delivery, unwavering control, and completely uncolored reproduction.

The MOON 888 does not strive to impress – it simply responds to every nuance with extreme precision.

Chassis Built for Perfect Silence

Each MOON 888 is milled from a single massive block of aluminum, providing optimal mechanical and thermal isolation for the signal path. This uncompromising construction minimizes microphonic effects, supports passive cooling, and preserves circuit integrity. The amplifier's massiveness is not a decorative choice – it is a structural solution that ensures mechanical stability and long-term performance. Thermal regulation remains consistent, and each unit is hand-assembled and tested in Montreal, Canada, adhering to the same strict quality standards as the entire MOON product line.

Effortless Listening at All Scales

The MOON 888 adds no color or emphasis – its ability to deliver pure and immediate power makes it disappear behind the music, even at high volumes. Complex audio materials – vast orchestral works, electro-acoustic textures, and wide dynamic variations – remain clear and nuanced without compression or listening fatigue. A high damping factor ensures complete speaker control without stiffening the sound. In a highly precise reproduction system, the MOON 888 acts as a silent foundation – unwavering, precise, and present in every detail.
