Internally it boasts a modular amplifier layout, powered by a power transformer that the brand describes as "super-silent". Combined with a fanless chassis and a heatsink design, the amp has been conceived to perform without unwanted noise.

Musical Fidelity says that its modular approach yields a high dynamic range and detailed soundstage, with a signal-to-noise ratio of 105dB @ 1kHz / 200W and THD + N of 0.003 per cent with100 watts power output.

The M6x 250.7 can connect to a multi-channel pre-amplifier or AV receiver, with physical connections including balanced XLR and unbalanced RCA inputs for each channel as well as line-level RCA outputs per channel for bi-amplifying. The amp also sports isolated speaker output terminals, which are gold-plated; meanwhile, a trigger in-out means the amp can be powered on/off externally.

The Musical Fidelity M6x 250.7 is now available in the UK, priced at £3099 / AU$6400 (around US$3388), with 5-channel (expected at AU$5750) and 11-channel (AU$7400) versions of the same design forthcoming.

    If only MF would release a replacement for the B1, in spec, performance and price. Something to go for instead of the ubiquitous Marantz X000X

    I had my B1 for 30+ years. I only gave up on it because I needed digital inputs.
