Over the last 40 years Musical Fidelity have produced a wide range of Pre/Power amplifiers from their very first product "THE PREAMP" to the latest Nuvista Pre/Power amplifier seen publicly for the first time at the 2022 Munich HiFi Show.
Some of the most successful British power amplifiers have been designed and manufactured by Musical Fidelity - The A370 won many accolades from both the media and the audiophile public from around the world. Followed by the likes of the astonishing F-series pre and power amplifiers which pushed the brand further in its quest for sonic perfection at realistic prices. Even more pre/power amplifiers followed, the likes of the Nuvista, Tri-vista and Kw series, resulting in the formidable Titan stereo power amplifier and the incredible PRIMO - all valve pre-amplifier. The circuit topology of the Titan power amplifier has found the way into many of the current amplifiers that Musical Fidelity manufacture today, including M6 and M8 pre-power amplifiers.
This continuing progress has now culminated in the Nuvista pre-power amplifier which the company hopes to launch in late 2022 or early 2023
Musical Fidelity M6s Pre-Amplifier
£1649.00 in Black or Silver
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, 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.

Musical Fidelity M5si Integrated Amplifier
£2599.00 in Black or Silver
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.

Musical Fidelity M8s Pre-Amplifier
£3999.00 in Black or Silver
The M8s is a pre-amplifier without limits. From its performance to its connectivity, via quality fit and finish, the M8s makes a superlative centrepiece for almost any system.
The M8s has a wide array of inputs including a low noise MM/MC phono stage, 2 balanced inputs (1 with home theatre bypass option), 3 line inputs (one with home theatre bypass option) and a fully configured tape in/out loop.
The M8s Pre-amp has very high input overload margins. This means that it has a completely stress free sound. The outputs are very low impedance and high current so that it can drive virtually any power amp in existence through any length cable (balanced or single ended).
Technical measurements are testament to the M8s’s exceptional engineering: from ultra-low distortion to virtually perfect frequency response, and ultra low noise.
The M8s’s will drive any power amplifier over any length of cable. Although, obviously, it’s perfect partner is a pair of M8s-700m monobloc amplifiers.
Listening to the M8s Pre with the M8s-700m monobloc is quite an experience. The music is reproduced with no stress, no colouration and sense of relaxation and transparency that are music to the ears and balm to the soul.
Design + Build
The first exceptional element of the M8s pre-amplifier is its truly fully balanced design. Most rival pre-amps making similar claims are actually single-ended models with a balanced input and output; this is not the same as being fully balanced throughout, which the M8s offers.
The quality continues with the M8s pre-amplifier's pure Class A circuitry, implemented in subtle and refined configurations.
The M8s is designed with very high input overload margins. High input impedance plus low output impedance puts the M8s in the position of itself being easy to drive, while having the capability to drive any power amp.
Let's run through those input options in more detail. The phono stage is a low-noise MM/MC design, with very accurate RIAA, low distortion and wide overload margin – all making the M8s a great turntable partner.
Two fully balanced inputs, three line-level inputs and a fully configured tape loop (input and output) provide plenty of flexibility for further sources, both traditional and modern.
Home theatre bypass options are available on one set of both balanced and line-level inputs, making it easy to integrate the M8s into a one-stop music and movie system.
The M8s's high-tech design translates into an exceptional performance that can be scientifically measured. Technical analysis shows the M8s has miniscule distortion levels (less than 0.003%), extremely low noise (-117dbA), wide bandwidth (-3dB 75kHz) and remarkable frequency response – ruler-flat within the audio band. Stereo separation is 96dB at 1KHz.
Finally, the M8s pre-amp also features an exceptional power supply. Each channel has a 350VA, silent-drive mains transformer, with each stage of each channel featuring its own regulation circuitry for optimised performance and isolation. Current delivery is maximised due to the power supply's ultra-low impedance design.
