It comes with a 10-year warranty for the first owner and has been designed to be easily repairable and potentially upgradeable in the future.<\/p>\n\n\n\n<p>To achieve this, the designer simplified everything that could be simplified and went back to the essence of what an amplifier should be: a machine that is faithful to the music and able to satisfy its owner for many years.<\/p>\n\n\n\n<p>Consequently, anything that was not absolutely essential to these specifications has been purely and simply eliminated. The TMA has no remote control or display; just a switch, a source selector and a volume control.<\/p>\n\n\n\n<p>These cosmetic savings have made it possible to focus on the quality of design and manufacture. It draws on 20 years of cumulative experience in the development of amplifiers, digital sources, cables and accessories. Nevertheless, it took three years to develop the TMA. Because behind its apparent simplicity, many essential details have been developed in terms of electronics, mechanics and cabling.<\/p>\n\n\n\n<p>The quality of the manufacturing relies on French and European subcontractors selected for the care they take in their work. The mechanical parts, the electronic card, the assembly and the packaging are all made in France. The transformer is made in Spain.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/vumetre.com\/wp-content\/uploads\/2025\/04\/VUmetre-50-4-NEODIO-TMA-3.webp\" alt=\"neodio tma amplifier hifi rear view connections\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>The chassis, mechanically welded for rigidity, has a non-conductive 6 mm PMMA rear panel. This provides mechanical decoupling and reduces electrical coupling between the various connectors (mains &#8211; HP &#8211; inputs). The chassis rests on three machined Delrin feet, another important detail. The two rotary knobs are machined from solid aluminium. On the scales, the TMA weighs in at a respectable 14 kg.<\/p>\n\n\n\n<p>The TMA uses a classic three-stage architecture with a high level of negative feedback. Negative feedback is a very effective technique, provided that attention is paid to the practical details of its implementation.<\/p>\n\n\n\n<p>The output is entrusted to special MOS transistors for audio with high current capacity (16 A). The driver stages are powered separately from the power supply and incorporate shunt-type regulation. The layout has been designed with the utmost care to avoid electromagnetic coupling. The components used were selected following numerous listening tests and based on experience gained with the brand&#8217;s CD players. The TMA also has overload and short-circuit protection, which has the advantage of protecting both the amplifier and the speakers.<\/p>\n\n\n\n<p>The power supply uses a 300 VA toroidal transformer with low noise and low losses, followed by several rectifier bridges and a capacitive filter totalling 44,000 uF, a very comfortable value for a 2 x 80 W amplifier. It uses only Vishay 105\u00b0C capacitors.<\/p>\n\n\n\n<p>The layout of the printed circuit board is deliberately \u2018airy\u2019 to make it easy to read and to allow for easier repairs in the future. According to the brand, an experienced technician should be able to repair this amplifier in 30 years, even without the electronic diagram.<\/p>\n\n\n\n<p>The choice was made to use components that guarantee the best sound quality and good durability, as evidenced by the RCA inputs with high-quality insulated and gold-plated plugs, the high-current capacity, low-mass nickel-plated speaker terminals and the speaker wiring made with the new Neodio Fractal 8 wire (eight strands of twisted copper insulated in a pseudo-random manner and covered with cotton).<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>The set-up<\/strong><\/p>\n\n\n\n<p>It&#8217;s hard to make something simpler and more direct than this new amplifier. In the box, you will find only it! No remote control, because it requires circuits that could degrade the sound and incidentally increase the price of the device. No power cord either, because at this level of quality, the manufacturer believes that you should certainly have a high-quality one. If this is not the case, he will direct you to one of his two models PC2, P5 or P70, which are not too expensive. There is no phono input either, as there are plenty of these on the market, of excellent quality, even at very affordable prices. For the connectors, you will only find RCA and female banana plugs, but of unquestionable quality. On the other hand, the device is delivered with excellent quality Andelle Rain support feet, which will give it excellent stability and good insulation from external vibrations. So to summarise: less, but better!<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/vumetre.com\/wp-content\/uploads\/2025\/04\/VUmetre-50-4-NEODIO-TMA-4.webp\" alt=\"neodio tma amplifier hifi close-up logo view\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>The sound<\/strong><\/p>\n\n\n\n<p>St\u00e9phane Even&#8217;s creations are interesting because his research scope is generally broader than average. This means that he is keen to explore all the components of an audio device. He ventures down sometimes very surprising paths deserted by his competitors. That is why this device sounds particularly satisfying. The first few minutes are enough to form a fairly comprehensive opinion of its behaviour. And the future will show that it will evolve relatively little thereafter. That is to say that the TMA is an easy amp that gives itself up easily and provides intuitive and liberated sound reproduction. In its company, most musical messages are savoured with relish. Whether you listen to vinyl, high-resolution digital audio files or compact discs, you will always enjoy it. Its power of seduction is expressed first and foremost in a full and relatively dense sound balance. The timbres have a beautiful thickness and a natural colour. Nothing particularly demonstrative or attention-seeking, but a real personality linked to a quality resolving power. The TMA is precise, both in its careful handling of small signals and its respect for their nuances, but above all in its ability to reproduce energy flows very well. In fact, this is its greatest quality in our view: an innate ability to never convey a smooth and monotonous message. On the contrary, the records pass with a very wide variety of intensity. TMA does not seek to make something systematically beautiful. On the other hand, it is very good at offering us an in-depth vision of each recording, highlighting its own characteristics. This means that we never get bored in its company. It does justice to the variety of your record collection, offering a unique and singular perspective on each of your records. We appreciated its ability to easily power a large number of speakers, even in a large room. We also liked its very good bass quality, which is deep, taut and muscular. Finally, like all good amplifiers, it manages to recreate a very beautiful three-dimensional space that fills the listening room with conviction.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/vumetre.com\/wp-content\/uploads\/2025\/04\/VUmetre-50-4-NEODIO-TMA-5.webp\" alt=\"neodio tma amplifier hifi front view\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Notre conclusion<\/strong><\/p>\n\n\n\n<p>We greatly appreciated the approach of the designer of Neodio. The anti-obsolescence, timeless and totally repairable aspect is very appealing. The Neodio TMA is an excellent integrated amplifier offered at a very reasonable price considering its performance. It is carefully constructed in France, and that too must be emphasised. We don&#8217;t know if it is the best amplifier offered by Neodio since its creation, but what we can tell you is that it is our favourite!<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Author<\/strong>: Laurent Thorin<\/p>\n\n\n\n<p><strong>Technical sheet: NEODIO TMA<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Origin<\/strong>: France<\/li>\n\n\n\n<li><strong>Price<\/strong>: \u20ac4,590<\/li>\n\n\n\n<li><strong>Dimensions<\/strong>: 445 x 390 x 130 mm<\/li>\n\n\n\n<li><strong>Weight<\/strong>: 14 kg<\/li>\n\n\n\n<li><strong>Power<\/strong>: 2 x 80 W\/8 ohms with current protection<\/li>\n\n\n\n<li><strong>Sensitivity<\/strong>: 440 mV<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>With the Neodio TMA, which stands for \u2018The Minimalist Amplifier\u2019, Neodio wants to extend its anti-obsolescence message by offering an amp designed and built to last and to be easily repaired.
