Description

M6X 250.4/2 | POWER AMPLIFIER

The M6x 250.4/2 is a 4/2 channel class A/B power amplifier.

You buy CDs or stream music without a picture, but have you ever watched a movie without sound? The sound of a movie is a significant part to deliver emotions and tell stories. Silence is as important as loud and engaging scenes. Sound designers use sound effects, foleys and music for sure to enhance your experience. A soundbar can never reproduce a real cinema feeling. The M6x 250.4/2 will take your home cinema to the next level.

The perfect expansion

The new M6x 250.4/2 is the choice for expanding your home theater system.

Power your main L/R channels, in its powerful bridged amplifier mode. Are you switching from 5.1 to 7.1? The M6x 250.4/2 gives you 2 channels of powerful bridged amp power for that too. Or use all 4 channels when upgrading your 7.1 system to a fully decked out 11.1 beast.

It‘s also perfect for anyone wanting to turn their 2-channel HiFi stereo setup into a cinematic 5.1 surround experience. The 4 channels of the M6x 250.4/2 allow you to power center and both surround speakers as well as your subwoofer.

You can connect your preamplifier/AV processor with either RCA or fully balanced XLR cables. The XLR connection furthermore enhances the sound quality and keeps the signal transmission clean.

The M6x 250.4/2 will not only satisfy you with its sound quality, but also with the high quality metalwork and overall clean look. The front panel in either black, or silver finish, is a custom-made fine line aluminium extrusion.

Connection

The new M6x 250.4/2 offers one gold-plated RCA and one balanced XLR input per channel. If you have XLR outputs on your preamp, we always recommend using a balanced connection. This kind of signal transmission leads to increased dynamics, less noise and improved signal-to-noise ratios. If you need the same signal on multiple inputs for e.g., bi-amping, you can use the gold-plated RCA through output and distribute the signal to the next input. The gold-plated isolated speaker output terminals accept 4 mm Banana plugs, spades connectors or naked wire. The trigger in-/output allows you to turn the device on/off via other components.

Power

Our new multichannel amplifier is built modular with one class A/B amplifier stage per channel. We designed our amplifier to sound highly natural by keeping all transients and micro information. The super silent audiophile power transformer distributes clean power, which results in a high dynamic range and a detailed sound stage. This is a major feature for a home cinema amplifier. The M6x 250.4/2 is able to preserve all the details and emotion, no matter which volume. Due to the sophisticated heat sink design, the M6x 250.4/2 does not need a fan to keep the amplifier cool. Despite its big power, you will never hear any fan noise coming from the amp.

Why Choose Musical Fidelity

Musical Fidelity is a British Hi-Fi manufacturer with a long-standing reputation for producing powerful, musically engaging amplifiers and source components designed around one simple philosophy — deliver big, effortless sound without unnecessary complication. Since the company’s beginnings in the 1980s, Musical Fidelity has developed a loyal following through products that combine strong engineering, substantial power delivery, and a highly enjoyable analogue-inspired presentation.

What makes Musical Fidelity particularly distinctive is the company’s focus on real-world amplifier performance and current delivery. Rather than chasing minimalist specifications or ultra-clinical presentation, Musical Fidelity products are engineered to sound expansive, confident, and highly musical across a broad range of loudspeakers and listening environments.

At HeyNow Hi-Fi, Musical Fidelity products consistently appeal to customers seeking amplifiers that combine authority, warmth, and strong system flexibility while still maintaining genuine high-end performance credentials. There is a sense of scale and ease to the sound that works beautifully with both digital and analogue systems.

Signature Design and Sound

Manufactured around substantial analogue amplifier platforms, Musical Fidelity products are engineered with oversized power supplies, high-current output stages, and strong emphasis on maintaining musical dynamics and tonal body even at lower listening levels.

The current B Series and M Series products in particular have attracted extremely strong international reviews for their ability to combine modern connectivity with the company’s traditional amplifier strengths. One especially useful feature within the newer range is the inclusion of HDMI eARC connectivity, allowing customers to integrate television audio directly into high-quality stereo systems without additional switching hardware or unnecessary complexity. For many customers, this creates a far more engaging alternative to conventional soundbars while maintaining proper Hi-Fi performance for music listening.

Musical Fidelity also continues to place strong emphasis on analogue integration, with many products incorporating high-quality DAC stages, moving magnet and moving coil phono preamplifiers, balanced connectivity, and substantial speaker-driving capability within highly versatile integrated amplifier platforms.

Sonically, Musical Fidelity products are known for their scale, warmth, and effortless dynamic presentation. The sound feels full-bodied and spacious, with strong bass authority, smooth tonal balance, and impressive long-term listenability. Rather than sounding overly sharp or analytical, the presentation remains inviting and highly musical while still preserving excellent detail retrieval and control.

Musical Fidelity Product Range

The Musical Fidelity range available through HeyNow Hi-Fi focuses primarily on the highly regarded B Series and M Series amplifiers, DACs, integrated amplifiers, and digital playback components designed for customers seeking strong amplifier performance together with modern system flexibility.

Products within the range combine substantial current delivery, refined analogue presentation, extensive connectivity, and practical integration features including HDMI eARC support, making them particularly attractive for modern stereo systems that integrate both music and television playback.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with speaker matching, television integration, analogue setup, streamer configuration, and complete system optimisation to ensure Musical Fidelity products perform at their full potential within each customer’s listening environment.
