M6s PRE Description
The M6s PRE is a fully balanced pre-amplifier, from beginning to end. Many pre-amps claim to be balanced but in fact are single ended preamps with balanced inputs and balanced outputs. However, the M6s is the real deal.

Its pure Class A circuitry with Surface Mount Devices (SMD) produces very low distortion, minimal phase shift, low noise and excellent linearity. Similarly, the low impedance output stages (both single ended and full balanced) will drive any power amp through any conceivable length of cable, for absolute reliability in performance.

The M6s PRE also features a wide range of inputs, making it the ideal system hub for any high-end audiophile. With two balanced XLR inputs and four unbalanced RCA inputs, the pre-amplifier also features a built-in asynchronous USB DAC capable of 24-bit/96kHz audio playback, and a switchable MM/MC phono stage. There is also the added convenience of a switchable RCA input for Home Theatre bypass.

For connecting on to a power amplifier, the M6s PRE offers both RCA and XLR outputs, as well as a fixed Tape loop for other system solutions. Operation is effortlessly simple via the front-panel buttons or supplied Musical Fidelity system remote.

The M6s PRE stands apart as a high-performance, high-end pre-amplifier that delivers superlative technical performance, great flexibility, excellent build quality and beautiful visuals. But where it truly delivers is when partnered with the powerful M6s PRX.

The M6s PRE and PRX are big, powerful high-end electronics that combine the expected Musical Fidelity sound signature with a range of features and technical specifications that make them a real feat of engineering. Available separately, or for a special bundle price they are a very exciting addition to the range that will delight audiophiles of all tastes and preferences.

M6s PRX Description

The M6s PRX is a fully-balanced dual-mono power amp for high-fidelity applications. Behind its classically simple, elegant design lies a true hi-fi monster that will drive any speaker with ease thanks to its 230 per-channel output (8Ω), delivering a deep and detailed sound stage that will leave you breathless.

The M6s PRX employs Musical Fidelity’s exclusive dual-mono, fully complementary, bifilar choke regulation system. Choke regulation is a concept taken from classic tube amplifier designs, but is rarely employed with transistor amplifiers. The implementation has huge power supply benefits, including a dramatic reduction in “saw tooth” power supply noise, and an effective mains noise filtration system. The dual mono, bifilar choke regulation system is unique to Musical Fidelity, and has been in use by them since 1987.

The M6s PRX’s audio circuitry is based on the classic Titan power amplifier design. It has eight output transistors per channel, and its technical performance is beyond the ability of most other power amplifiers on the market at any price. Extremely low wide-band distortion, low output impedance, outstanding load driving characteristics, enormous stability margins and very high peak current delivery mark the M6s PRX dual-mono power amplifier as a truly special, unique design for the price.

The M6s PRX is easy to integrate thanks to its switchable XLR and RCA inputs, and it can easily be partnered into a bigger system via the RCA Loop output.

When employed in any high-end system, the M6s PRX sounds effortless, detailed and fast without a hint of harshness. But if you want to guarantee the very best symbiosis and matching cosmetic appeal, the M6s PRX is ideally partnered with the M6s PRE pre-amplifier.

The M6s PRE and PRX are big, powerful high-end electronics that combine the expected Musical Fidelity sound signature with a range of features and technical specifications that make them a real feat of engineering. Available separately, or for a special bundle price they are a very exciting addition to the range that will delight audiophiles of all tastes and preferences.
