Musical Fidelity A1

In Hi-Fi, the Musical Fidelity A1 has become one of the most classic designs – inside and out. First released back in 1985, it quickly made waves for being an absolute beast when it came down to driving some of the most difficult speakers of that time, even though it was actually a rather low powered integrated amplifier. But: it was all done in pure Class A with excellent and expertly laid out discrete symmetrical circuitry topology and using only highest quality components. The A1 showed people that there was more to amplifiers than just high power.Based on its huge success, the A1 has gone through multiple reissues and new versions over the years.Now for 2023, for the first time since its initial release we have actually kept all specifications, the appearance and circuits of the 1985 rendition for those who missed out the first time. With an updated transformer, power supplies and modern low noise components we’ve revitalized the formula and are proud to reintroduce the fresh original – three decades later.Technical TalkThe A1 is built around a completely discrete and symmetrical Class A topology. It‘s able to output 25W of pure Class A power @ 8 ohms load with 25A of maximum output. While the numbers here might seem rather low, the ability for the output stage to drive difficult speakers is a small miracle in itself. The amp design being dynamic class A, and if Class A standing current is exceeded, it will automatically allow more. It therefore “slides” (NOT “switches”) smoothly into class B style operation, temporarily allowing the further current draw needed.Power SupplyThe new A1 has received an updated transformer from shared (1985 original) to more efficient “dual mono split rail” windings. The amp stages are supplied by fully independent left and right power supplies for better power handling and stereo imaging and each power amplifier now has double supply capacity resulting in reduced ripple and noise.The transformer‘s noise and heat dissipation are reduced due to better efficiency and updated components. The main supplies are filtered for better regulation and reduced switch on surge.PreamplifierThe low noise preamplifier circuitry is the same as the original 1985 design and, as we have highlighted above, greatly benefits from the improved, fully smoothed and regulated power supplies.Among the discernible alterations, one that immediately catches the eye is the addition of a new „direct“ switch at the preamp stage. With this switch you can totally bypass the gain block before the volume control, resulting in roughly 10dB less gain. This feature proves particularly advantageous when working with modern or high-output digital sources, enabling fine tuning the range of your volume potentiometer and accommodating sensitive loudspeakers.Furthermore, a notable upgrade has been made to the volume potentiometer itself, now replaced by a premium ALPS RK series potentiometer. This high-quality component ensures superior performance and enhanced precision. Additionally, the potentiometer is now motorized, granting you the convenience of adjusting the volume from the comfort of your couch, courtesy of the new included remote control.Phono StageThe A1 employs a discrete current-mode input stage for lowest noise amplification of MC and MM cartridges. A low noise current to voltage conversion stage is used for further amplification and RIAA equalization. Automatic input impedance matching for the selected MC input, along with increased gain increases the versatility of the A1‘s phono stage.The return of a true Hi-Fi classicThe A1 has one secret. This secret is simple: it makes music. It sounds sweet and fluid and creates a beautiful atmosphere around natural instruments. Especially in small to mid-sized rooms, carefully set up with a pair of great two-way speakers. It is not a powerhouse, but music lovers will cherish its abilities.It‘s also not a product that you‘ll want to hide. A perfect example of form follows function. The oversized heatsinks define the A1‘s look, but they are essential for its operation. Truly unique, from the outside and inside.The A1 has a sweet, warm, full and exciting sound. No harshness. No grain. Just pure music. It doesn‘t get muddy, and despite its lower power, drives difficult speakers with ease. It remains clean right up to its power limit. To hear what the A1 does is to hear what Hi-Fi is supposed to do: it makes music, pure and simple.The A1 through time - Improvements to the originalUpdated transformer to more efficient “dual mono split rail” windingsHigh quality and updated ALPS RK series potentiometer as volume controlIR remote control added for volumeGain block before volume control totally by passable using “direct” switch (-10dB)All transistors including output devices are carefully selected modern equivalentsAll capacitors in signal path are polypropylene (PP) typeResistors are modern low noise metal film typesCare and attention made to not change any component specification from original but to update them to modern equivalent with long lifespanLayout faithfully follows original within circuit sections on circuit boardCircuit sections better laid out, in particular the separate supplies and power amplifiersPhono stage and preamplifier improved for less noise and humThe A1 in Brief25W Pure Class A power @ 8 OhmDiscrete symmetrical topologyPlanar Audio transistors with 25A maximum outputDynamic class A, slides (NOT switches) smoothly into Class B, allowing more current as neededTherefore drives difficult speakers with no problemsUpdated transformer to “dual mono split rail” windingsFully independent left and right power suppliesEach power amplifier now has double supply capacityTransformer noise and heat dissipation reducedFiltered main suppliesGain block before volume control totally bypassable using “direct” switchHigh quality and updated ALPS RK series potentiometerLow noise TL071 JFET preamplifier circuitryDiscrete current-mode MM/MC phono input stageLow noise current to voltage converter for further amplification and RIAA equalisationAutomatic input impedance matching (1K nominal) for MC along with increased gainOriginal (1985) A1 appearance and circuits with modern improvementsRemote control added for volumeModern updated low noise components

Musical Fidelity M5SI Silver

The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one pcb. Its technical performance is about equal to the M6si. The M5si has very low distortion, outstanding noise ratio and an extremely flat frequency response. Inputs; phono (mm), 4 line, and USB ’B’ up to 24bit 96kHz. The M5si produces an extraordinary sweet clear lucid sound. Significantly it was developed after our amazing legendary Nu-Vista 800. Consequently some of the Nu-Vista 800’s subtle pcb layout solutions have found their way into the M5si. When you hear it we are sure you will understand the relationship between the two. The M5si projects a deep and wide stereo image with very extended bass and a crystalline top end without a trace of harshness.

Musical Fidelity M3x Vinyl Black

The M3x ViNYL is a phono stage, designed to be without any practical limits. Connectivity is straight forward. You have an input and an output. Neither of them can be overloaded at the input or limited in the output driving capacity. It can be set for either MM or MC and exact loading. It offers state-of-the art technical and sonic performance just like the M6x ViNYL, but at a cheaper entry level to the epitome of the true spirit of high-end audio. Design Philosophy The M3x ViNYL has been switched, just like in its bigger brother the M6x ViNYL, to an entirely discrete circuitry, which results in better technical measurements and better sound. It is equipped with one single-ended input and output. But the important question is: what is so special about discrete circuits? Although it is Musical Fidelity’s lowest price amplifier, it embodies our hallmark values of uncoloured, stress-free sound, outstanding technical performance and great value for money. The Advantage of Discrete Circuits A discrete circuit is composed of electronic components which are disparate, individual devices, also called discrete components. These can be “passive” components, like resistors, capacitors and inductors, as well as “active” components, which in our case are transistors. The opposite to this would be an integrated circuit, which uses operational amplifiers (Op-Amps) in the signal chain. In our industry we employ specialised Op-Amps built for audio applications, which allow us to produce very small and efficient electronics, as well as saving the time of design engineers. However, countless hours of listening tests and years of experience have shown us that even the very best Op-Amps do not tend to be so neutral, natural, dynamic or vivid – all of which are characteristics of the Musical Fidelity “sound”. For that reason, we’re rediscovering our passion for traditional, discrete designs. Where standard phono pre-amplifiers with integrated circuits have a few tens or hundreds of components, discrete designs will employ hundreds or thousands of components by comparison. That makes for an extended design process, but in our opinion results in the best sound for your money. Toroidal Power Transformer The special audio transformer with low core saturation decreases the level of electromagnetic radiation, which is essential because otherwise any phono amplifier will never be able to work correctly. Together with the distance between transformer and amplification section and the electromagnetic shielding, we are creating an incredibly high signal to noise ratio. If we are working with the few hundreds of microvolts from a phono cartridge, everything is playing its role; every decibel of signal to noise ratio is crucially important. For the first time, we have implemented our new proprietary power supply solution that has zero standby power consumption. Absolutely zero! It is a super green product and we are sure, there isn’t any other product in existence with an ecological standby function like this. Split Passive EQ Many other phono stages are using a single equalization network in a global feedback loop. By means of an EQ network, the amplified signal from the output of the phono preamp is brought back to the input of the phono preamp. This is the before mentioned feedback loop, and the results, as you can imagine, are not in accordance with the high standards in Musical Fidelity design philosophy. The M3x ViNYL uses split passive equalization in separate amplification stages without global negative feedback loops for its RIAA curve. This is more costly to design and implement but ensures the most accurate representation of the ideal EQ curve. Split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA curve. High-Tech Mechanical and Electrical Engineering - Hand Made in the EU M3x ViNYL has a steel chassis and a thick, heavy aluminium frontplate, which brings outstanding rigidity to the entire system and at the same time splendid isolation against outside interference. Key factor in keeping signal to noise ratios on the highest possible leveld is the huge distance between power transformer and amplifier section. The quality of the outside chassis finish, which is beyond beautiful, as well as the electronics inside - all wired by hand - is maintained by the highest manufacturing standards which we now achieve by fully switching the production to be entirely Made in the EU!

Musical Fidelity M8xi Black

In 1990, Musical Fidelity made the first-ever Super Integrated amplifier: the A1000. lt received a rapturous welcome and, even today, second hand, is selling at high prices. The A1000 was the first of a long line of Super Integrated Amplifiers from Musical Fidelity. Its children: the NuVista M3, Tri Vista 300, kW500, M6/500i, NuVista 800 and NuVista 600 all were equally enthusiastically welcomed to the audiophile world. The M8xi is the latest and the best of the breed. General Description The M8xi is a separate preamp with two monobloc power amps sharing a common chassis. Each has its own heat sink and separate transformer. Genuinely dual mono. The preamp has its own separate power supply and is mounted close to the input sockets. Consequently, PCB tracks are very short. This elegant idea ensures that both channels' signals are ultra-low impedance the instant they get into the amplifier. This is a significant detail. Each channel has twelve big bipolar transistors - 200 amps peak to peak is easily available. The metalwork is high quality. The front panel is a custom made fine line extrusion of milspec aluminum. The custom made heat sinks have outstanding dissipation characteristics and finish. The M8xi construction has a feeling of solidity and quality. New Circuitry Over the last 5 years our power amp circuitry has reached a high state of development. In our never-ending quest for improving performance and customer value we have been looking for ways to improve our designs. One of the prime directives was to keep the low feedback configuration unchanged .. continue with low feedback! The problem was how to improve efficiency and performance without affecting the sound quality. If I say so myself, I think we have come up with a brilliant solution. Our new M8xi power amp design gives higher power, lower distortion, and better sound quality. Incredible but true. The output stage efficiency has been increased thus yielding about 10% more power for similar power supply voltage. More importantly, the whole driver stage is pure Class A. We believe that this innovative approach has a substantial effect on the sound quality. The sound stage appears wider whilst the micro and macro dynamics have more impact. This effect is particularly noticeable on well-recorded piano. I am sure you all know the piano is a percussive instrument but in truth, this is rarely audible on most Hi-Fi systems. Using an M8xi a piano‘s percussive nature becomes instantly obvious and jumps out of the loudspeaker. lt is a surprising and satisfying improvement to the sound quality. Vocals have more subtly, detail and presence. Large scale music has depth, width, and incredibly dynamic presentation. All in all the M8xi is a consummate all-rounder. Mostly it sounds like a small Class A amplifier with huge power. The DAC The M8xi also features a 5 input DAC. DACs are increasingly common in integrated amplifier designs to add convenience when connecting a variety of digital sources, so the decision was taken to build-in a DAC that would perform to a high standard, independently of the amplifier. For added integrity, the DAC features its own power supply. Based around the Texas Instruments PCM5242 TI low-distortion and low-noise DAC chip, which is also employed in many other premium products in the hi-fi industry as well as in previous Musical Fidelity products, the M8xi has 2 x coaxial (S/PDIF), 2 x optical (S/PDIF) and 1 x asynchronous USB Type-B inputs. The coaxial and the USB inputs are capable of supporting hi-res audio streams up-to 24-bit / 192kHz, and the optical input is capable of supporting up-to 24-bit / 96kHz. For maximal performance, all data streams are up-sampled and re-clocked by an internal converter to reduce jitter and remove unwanted artifacts in the sound. Technical Performance The M8xi delivers 550 + 550wpc into 8 ohms. It is extremely stable and very linear. The distortion is low too; lower than 0.005% in the audible frequency range of 20 Hz to 20 kHz. The M8xi has remarkable linearity and consistency. lt is unconditionally stable and will drive any loudspeaker in existence easily with ample power reserve. Our Approach to Technical Measurements In our view an amplifier should be completely neutral. lt is ‚a straight wire with gain‘. Easy to say but hard and complex to do. We want to stress that we do not believe that the technical performance is an end in itself. lt is a method of validating the total amplifier system concept. The aim of our circuit/PCB designs is to have low feedback and achieve complete neutrality, transparency, and great technical performance. The proof that we are on the right track is the technical performance. We think that technical performance cannot be summed up by the distortion at 1 kHz. Our view is that an amplifier has to be able to satisfy a wide range of technical requirements before it can be neutral. Linearity Almost all loudspeakers have complex impedance and loading curves. An amplifier must be able to maintain its voltage virtually, regardless of loading. If an amplifier cannot maintain its voltage across the spectrum, then the ultimate frequency response and distortion will be nonlinear. This is not neutrality. Distortion The overwhelming majority of amplifier manufacturers only talk about distortion at 1 kHz. We believe that this is only a fraction of the story. From our perspective, an amplifier must have very low distortion from 20 Hz- 20 kHz and beyond. We believe that an amplifier‘s high-frequency performance proves the total performance of the circuit and PCB layout. The M8xi distortion hardly changes from 10 kHz to 50 kHz. An outstanding achievement and validation of the circuit design and PCB layout. Noise Ratio Amplifiers should be quiet. If they are not, low-level detail is irretrievably lost. Also, the dynamic range is seriously compromised. Dynamic range is not just how much power an amplifier will produce, it is also how quiet it can be. Dynamic range is the total from the quietest to the loudest. The M8xi excels in this respect. Precision Volume Control The M8xi has a precision volume control. This ensures perfect tracking right down to very low levels which is unattainable with standard potentiometers. This outstanding precision is achieved by laser-trimmed substrate resistors. Sound Quality The M8xi is effortless, fluid, and dynamic. lt doesn‘t sound ‚loud‘. lt just sounds right. The dynamics are handled with no drama or fuss. They come and they go. There is no distortion; just pure undiluted music. lt sounds like a superb small Class A amplifier but with limitless headroom. Perfection!
