Product Description

Musical Fidelity M6SPRX Power Amplifier is a fully-balanced dual-mono power amp for high-fidelity applications. Beyond its simple, elegant design lies a true hi-fi performer that will drive any speaker with ease due to its 230 per-channel output (8Ω), delivering a deep and detailed sound stage that will leave you breathless.

Dual Mono Design

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 power supply noise and an effective mains noise filtration. The dual mono, bifilar choke regulation system is unique to Musical Fidelity and has been in use since 1987.

Audio Circuitry

M6S PRXs audio circuitry is based on the classic Titan power amplifier design with 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 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 larger 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.

Pair with M6SPRE

If you want to guarantee the very best symbiosis and matching cosmetic appeal, the M6s PRX is ideal when partnered with the M6s PRE pre-amplifier. These big, powerful high-end electronics combine the expected Musical Fidelity sound signature with a range of features and technical specs that make them a real feat of engineering. Available separately or for a special bundle price this is a very exciting addition that will delight audiophiles of all tastes and preferences.

- Extremely low wide-band distortion levels
