Know before you buy
By housing two independent power amplifiers within one chassis, the M6si ensures that the left and right channels remain completely separate. This design minimizes crosstalk and interference, resulting in superior channel separation and a more precise, stable soundstage.
Yes, the amplifier features a high-quality built-in phono stage that supports both Moving Magnet (MM) and Moving Coil (MC) cartridges. It is designed for accurate RIAA equalization, so you do not need an external phono preamp.
The home theater bypass allows you to integrate the M6si into a surround sound system by letting an AV receiver control the volume for the front speakers. When engaged, it effectively turns the M6si into a dedicated power amplifier for your main left and right channels, maintaining high-end performance for music while allowing for seamless home theater operation.
The onboard asynchronous USB input supports audio streams up to 24-bit/96 kHz. Its asynchronous design helps eliminate jitter, ensuring that digital audio from your computer is processed with high clarity and detail.
With 220 watts per channel into 8 ohms, the M6si is exceptionally powerful and designed to drive almost any loudspeaker with ease. Its high current capability ensures it maintains control and low distortion even during demanding musical passages.
The M6si measures 17 inches wide, 4.9 inches high, and 15.7 inches deep. It weighs 36.6 pounds, so ensure your shelving unit is sturdy enough to support its weight and provides adequate ventilation for the internal components.
