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.
