Musical Fidelity M6x 250.7 power amplifier

“Best Product Home Theater Power Amplifier” – EISA Awards 2023-2024

This multi-channel wonder is designed for high-end home theater speakers that require power. The M6x 250.7 offers all seven channels a power of 150 watts, combining great dynamics with powerful, transparent and rich sound reproduction. The amplifier is housed in a sturdy metal case with a thick aluminum front panel. The device contains two Musical Fidelity “Super Silent” toroidal transformers that supply power to seven separate amplifier modules, each with its own cooling system. The device has bi-amp capability thanks to the chained outputs, and the user can choose either balanced or unbalanced connections.

The M6x 250.7 is a 7-channel A/B class power amplifier.

You listen to CDs or stream music without picture, but have you ever watched a movie without sound? The sound of a movie carries a significant part to deliver emotions and tell stories. Silence is as important as bombastic loudness. Sound designers use sound effects, foleys and music to enhance your experience. A soundbar can never reproduce a real cinema feeling. The M6x 250.7 will take your home cinema to the next level.

The Full Cinematic Experience

For many people, the cinema is just a place with a big screen and expensive snacks – but there is more, which is usually not visible at all: The surround sound system. It all started with a simple three speaker setup in the 1980s and evolved to object based systems with up to 20 speakers. With the new M6x 250.7 you can easily create a powerful 7.1 home cinema setup (your active subwoofer is powered separately). You can connect your preamplifier/AV processor with either RCA or fully balanced XLR cables. The XLR connection further enhances the sound quality and keeps the signal transmission clean.

The Musical Fidelity M6x 250.7 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 aluminum extrusion.

Connection

The M6x 250.7 offers a gold-plated RCA and a 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 eg, 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 bare 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 250W 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 250.7 is able to preserve all the details and emotion, no matter which volume. Due to the sophisticated heat sink design, the M6x 250.7 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.
