Musical Fidelity B1xi: the high-performance integrated amplifier for less than €1,000!
In the world of Hi-Fi, certain products mark a turning point. The Musical Fidelity B1xi belongs to that rare category of amplifiers that reconcile audiophile performance and affordability. While the market often offers a binary choice between entry-level equipment with obvious sonic compromises and high-end solutions that are financially out of reach, Musical Fidelity dares to take a third path with this new integrated amplifier for less than 1000 euros.
In this article, we explain why a quality amplifier is the heart of any successful audio setup, how to choose the right amplifier for your needs, and how the Musical Fidelity B1xi truly stands out from the competition. We also answer frequently asked questions about amplifiers to help you make an informed and lasting choice.
What is an amplifier and why is it essential in a Hi-Fi system?
At the heart of any Hi-Fi system is the amplifier, the true conductor of your audio system. An amplifier performs two essential functions: preamplifies weak signals from your sources (turntable, CD player, DAC) and amplifies the power needed to drive your speakers.
Without a quality amplifier, even the best speakers and sources will fail to reach their full potential. It’s the element that transforms a simple electrical signal into a coherent, dynamic, and emotional musical experience.
What is the difference between an integrated amplifier and other types of amplifiers?
There are three main types of amplifiers:
- The integrated amplifier: combines preamplifier and power amplifier in a single enclosure
- The preamplifier: manages source selection and volume control
- The power amplifier: only amplifies the signal to power the speakers
An integrated amplifier like the B1xi is the ideal solution for getting started in Hi-Fi: it offers simplified installation, optimal sound consistency and excellent value for money. For beginners building their first Hi-Fi system, this configuration avoids compatibility issues between separate components.

Why choose an amplifier without integrated streaming?
One of the most relevant decisions of the manufacturer concerns the deliberate absence of integrated streaming functions, this philosophy is based on a technical observation: all-in-one amplifiers with streaming age quickly, become obsolete and are generally less efficient in terms of audio.
The B1xi focuses on the essentials: flawless amplification and high-quality digital conversions. For streaming, you can easily connect and lecteur réseau Bluesound Node via digital inputs or opt for a streamer Cambridge Audio MXN10 which will combine perfectly with the capabilities of the B1xi . This approach guarantees the sustainability of your investment over time.
How to choose an amplifier suitable for your speakers?
Is a more powerful amplifier always better for my speakers?
No, power is not the only criterion of quality. What really matters is:
- The quality of amplificationand the linearity of the circuit
- The ability to deliver currentin a stable manner
- The impedance of your speakers(4 or 8 ohms)
- The volume of your listening room
The B1xi delivers 100W into 4 ohms and 60W into 8 ohms thanks to its powerful Class A/B circuitry. These figures may seem modest, butIt’s the power reserve that makes the differenceThis technical parameter allows the B1xi to effectively control a wide range of speakers, including demanding models.
Can the B1xi amplifier power hard-to-drive speakers?
Yes, the Musical Fidelity B1xi is designed to drive demanding speakers. Whether you have floorstanding speakers TESI 5 or bookshelf Sprint 3, the B1xi will know how to pilot them with authority and finesse.
The low-frequency control is particularly impressive for this price range, providing a firm bass foundation without ever aggressively projecting the high end. For a room of 20 to 40 m², the B1xi‘s power is more than sufficient.
What is Class A and why is it important?
Class A represents the most linear amplification mode, where the components are constantly working in their optimal operating zone. The B1xi‘s preamplifier operates entirely in class A, a feature rarely found on an amplifier under 1000 euros.
Advantages of Class A:
- Exceptional transparency of the audio signal
- Dynamics preserved without compression
- No crossover distortion
- Natural reproduction of stamps
This architecture explains why the B1xi‘s sonic balance sometimes evokes that of a tube amplifier., without the maintenance constraints (changing tubes, preheating). The accuracy of the timbre, a crucial parameter for faithfully reproducing acoustic instruments and voices, becomes obvious when listening.
| Class | Operating principle | Benefits | Disadvantages | Typical use |
| Class A | Transistors conduct continuously | Linearity, maximum sound purity | High heat, low efficiency | High-end amplifiers |
| Class B | Each transistor handles one half of the signal | Efficient, low heat | Crossover distortion | Economical amplifiers |
| Class AB | Simultaneous partial conduction | Balance between warmth and precision | Performance compromise | High-end Hi-Fi |
| Class D | Switching Mode Modulation (PWM) | Very efficient, compact | Less natural on certain timbres | Home cinema, portable |
How to connect a turntable to an amplifier?
To connect a turntable to an amplifier, a dedicated phono input is essential. Magnetic (MM) or high output (high level MC) phono cartridges generate an extremely low signal (a few millivolts) which requires:
- Specific amplification (40 to 60 dB gain)
- Accurate RIAA equalization
- Minimal background noise
The B1xi’s phono input: a benchmark in its category
The B1xi integrates an MM phono input with its own dedicated linear power supply, a rarity in this price range. This physical separation guarantees:
- Ultra-low background noise (exceptional signal-to-noise ratio)
- Excellent channel separation (stereo isolation)
- Performance rivaling some separate phono preamplifiers
With a high gain of 42 dB and a sensitivity from 1.5 mV, this phono input will perfectly accommodate your platine Pro-Ject Debut Carbon EVO II equipped with its original cell, or a Rega Planar 3 for those who want to move upmarket.
What is a DAC and why is it important?
A DAC (Digital to Analog Converter) is a digital-to-analog converterwhich transforms digital files (FLAC, WAV, MP3) into an analog signal that your amplifier can process. The quality of the DAC directly determines the reproduction of your dematerialized music.
The ESS Sabre ES9018 chip: excellence in digital conversion
Musical Fidelity has equipped the B1xi the ESS Sabre ES9018 chip, a benchmark in the field of audiophile DACs. This architecture offers:
- Asynchronous signal processingup to 24-bit/192 kHz
- High definition resolutionpreserved
- Minimal harmonic distortion
- Extended dynamicsfor demanding recordings
The B1xi has multiple digital inputs:coaxial, optical Toslink and HDMI ARC. The latter allows for elegant integration with your TV for occasional home theater use. Bluetooth connection completes the connectivity for relaxed listening from a smartphone.
Optimized audio architecture: analog/digital separation
A revealing detail of the attention paid to design:The digital and ARC cards are physically separated on their own circuit boardsand have their own linear power supply. This architecture prevents any pollution of the analog stages by the digital circuits, thus preserving the purity of the audio signal.

What questions should you ask before choosing an amplifier?
1. What is the impedance of my speakers?
Impedance (expressed in ohms) measures the electrical resistance of your speakers. 4-ohm speakers are more difficult to drive than 8-ohm speakers. The B1xi handles both with ease thanks to its robust design, but this question remains central to any amplifier choice.
2. What are my current and future sources? ?
- Do you own avinyl turntable? → The B1xi‘s MM phono input is essential
- Do you mainly listen todigital files? → The ES9018 DAC guarantees optimal quality
- Do you use thestreaming? → Connect an external streamer via the digital inputs
- Are you looking atfilms? → HDMI ARC input simplifies integration
The B1xi covers all these needs without requiring additional equipment to get started.
3. What is my listening environment?
The size of your room influences the power required :
- Less than 20 m²: 30-50 W is generally sufficient
- 20 to 40 m²: 50-100 W recommended (ideal area of B1xi )
- More than 40 m²: choose 100 W and more
4. What budget should I allocate to the amplifier?
An amplifier represents about 30 to 40% of the budget of a balanced Hi-Fi system the B1xi‘s price positioning at less than 1000 euros allows the remainder to be allocated to quality speakers and sources, thus creating a coherent system.
