Stereo Class D Amplifier TPA3255 2x225W 4 Ohm

FOSI AUDIO V3 Amplificateur Stéréo Class D TPA3255 2x300W 4 Ohm

The V3 from Fosi Audio is a compact, powerful amplifier that also remains very affordable. Despite its simplicity, the V3 amplifier uses high-quality audiophile components such as a TI TPA3255 amplification chip, Japanese and German Elna and Wima capacitors and DIP8-mounted NE5532 AOPs, giving you the option of replacing them if you want a particular sound signature. This amplifier is ideal for integration into a HiFi system requiring high power, since it delivers up to 2x225W @ 4Ω. Connections include a stereo RCA input, speaker terminals and a 3.5mm pre-out jack.

A powerful amplification stage

The Fosi Audio V3 uses a TI TPA3255 amplification chip, which delivers true sound quality with class D efficiency and very low distortion. Coupled with audiophile components, the TI TPA3255 allows the V3 to maintain high stability even at very high power. In terms of OPA, the Fosi Audio V3 is equipped with DIP8-mounted NE5532, making them easy to replace. They can be replaced by MUSES02s, AOP2604APs or AOP2134PAs, for example.

Intelligent volume control

The volume control is based on a logarithm (Taper A pot), providing much finer control that is better adapted to the human ear. This makes the final listening experience more immersive and pleasant.

Efficient heat dissipation

The heat dissipation system of the Fosi Audio V3 allows it to be used at high power for extended periods without compromising its performance or causing harmful effects. In fact, the V3's enclosure incorporates vents on its upper and lower sides as well as an internal radiator. This innovative cooling system design greatly improves the airflow and heat dissipation of the Fosi Audio V3 amplifier.

Date :
Rapport qualité prix imbattable
Concernant la commande :
envoi le 19 en journée, reçu le lendemain midi !
Une alim en 48V fournie, le must.
Concernant l'ampli :
Taille lilliputienne, comme la plupart du matos hifi chinois.
Bonne qualité de finition (borniers enceintes minuscules, exigeant des fiches bananes)
L'écoute : (sur des LS50 et des Wharfedale Evo 4.4)
Du détail ! Le premier point de satisfaction pour moi.
La définition et la spatialisation sont excellentes.
L'écoute est encore plus "déliée" sur mon Topping PA5, mais de peu, et le Fosi pourra par conséquent paraître moins fatigant à l'écoute.
Les registres (aigus/médiums/graves) sont restitués équitablement d'après moi.
Et la réserve de puissance est bienvenue sur les enceintes à faible rendement (mes LS50 ont gagné en souffle avec le Fosi!).
Bref, du tout bon !

Just amazing
The sound quality and the power are just amazing. This tiny package delivers a great sound with really nice details and amazing sounding low frequencies. The 48 volt 5a version is a must.

Fosi V3 : une boule de nerfs !
En ouvrant le colis l'ampli paraît petit mais branchez le et c'est une boule de nerfs ! Très dynamique, neutre, le son est top. La gestion du volume est fine et précise.
Ce V3 (la dernière version) représente bien la Class D "moderne" avec tout ses avantages, dont le prix mais pas que ...
Très bien conseillé aussi !
Je vous le recommande vraiment pour son rapport Q/P.
Livré en 36h !!!
