Know before you buy
The M1 is designed for neutrality. It provides an uncolored, transparent sound reproduction that stays true to the original recording without adding its own character to the audio.
The M1 utilizes a specialized internal heat-pipe cooling system. This allows the amplifier to run silently without the need for noisy cooling fans, even when delivering high power output.
Yes, the M1 is specifically designed to be stackable. Its compact 1U form factor and efficient cooling system make it well-suited for multi-channel setups where space is limited.
The amplifier features both RCA and XLR inputs, providing flexibility for integration with a wide variety of preamplifiers and audio components.
No, the M1 is not bridgeable. However, with a continuous power output of 1,000W into 8Ω and up to 2,400W into 3Ω, it already offers significant power reserves for most demanding speaker loads.
No, the M1 is a dedicated monaural power amplifier and does not include a remote control or an integrated digital-to-analog converter. It is designed to function strictly as a high-performance power stage.
