Effortless Power and Control
With 220W per channel into 8 ohms (400W into 4 ohms), the M6si delivers high-current output that controls speakers with authority. Its class A/B amplifier stage is designed for stability under load, ensuring dynamics remain intact even with inefficient or large floorstanders. Total harmonic distortion is exceptionally low at less than 0.007 (20Hz–20kHz), meaning the sound stays clean and composed across the spectrum. Whether reproducing subtle acoustic detail or wide-scale orchestral peaks, the M6si delivers power that feels expansive, balanced and built for long listening sessions.
Engineered Like Separate Components
Internally, the M6si is split into three sections: a preamp and two completely independent monobloc power amplifiers. Each power stage has its own dedicated heatsinks, power supply and layout, minimising crosstalk and preserving signal purity. Channel separation is excellent at over 82dB at 1kHz, and frequency response remains flat from 10Hz to 50kHz. This approach delivers the imaging and clarity you’d expect from separate boxes, but with the practicality of an integrated amp. It’s a technical design focused on reducing interference and revealing more musical information.
Versatile Connectivity for Every Setup
The M6si supports a wide range of source devices through its generous I/O options. Analogue inputs include four RCA line-level, one balanced XLR and a switchable MM/MC phono stage with accurate RIAA equalisation. Digital users can connect via asynchronous USB (24-bit/96kHz) for computer-based playback. A fixed pre-out and home theatre bypass add further flexibility for system expansion. Signal-to-noise ratio is 107dB (line) and 90dB (phono), ensuring low background noise and full-resolution playback from vinyl, streaming or CD. It’s a fully equipped amplifier built to grow with your system.

Titanium Dome Tweeter With Grille Design
The Titanium Dome tweeter is shaped to control breakup behaviour so it stays accurate well above what you can hear. This gives you a cleaner and more stable top end with less distortion when you turn up the volume. The acoustically transparent grille mesh, first used in the brand’s Signature range, helps the tweeter spread sound more evenly. You get improved dispersion, a more consistent tonal balance and clearer spatial cues when listening to detailed recordings that rely on precise high frequency information.
Continuum Midrange And Driver Geometry
The Continuum midrange driver uses a flexible composite structure that avoids the sudden resonances often found in traditional cone materials. This creates smoother performance through the vocal range, helping complex recordings keep their separation and clarity. Its fixed suspension transducer surround supports more pistonic movement to reduce colouration and keep the midrange neutral. You hear clearer piano notes, cleaner guitar textures and more intelligible dialogue when using the speakers within a home cinema system, especially in scenes that rely on subtle midrange detail.
Dual Bass Drivers And Cabinet Integration
The dual bass drivers use a long throw motor system that stays composed during demanding low frequency peaks. This delivers confident extension that supports the music without masking the midrange. Their placement and the cabinet volume are matched to provide balanced loading, improving damping and reducing unwanted resonance. Bass notes remain tight and tuneful, even in larger rooms where low frequencies can easily become excessive. You gain more freedom with speaker placement because the bass response stays consistent across the room while still offering reliable depth and impact.
