With its S17 Pro, Aune unveils a powerful headphone amplifier that can also be used as a preamplifier in a Hi-Fi installation. This headphone amplifier features discrete components and balanced outputs. Its Class A amplification stage features a pair of JFET transistors for the headphone outputs, plus two AOPs per output for a total of 16 AOPs. It also features an R2R volume control and an attractive color display on the front panel. Inputs include stereo RCA and balanced stereo XLR. Powerful, the S17 Pro is capable of driving any type of headphone on the market, from 32Ω to 600Ω impedance.

A powerful amplifier stage

The Aune S17 Pro's amplification stage is made up of TWIN JFETs, ideal for headphone amplification. In addition, each output channel incorporates 2 pairs of transistors, giving a total of 16 transistors. This Class A headphone amplifier also features two levels of current adjustment: 50mA and 100mA per JFET. Overall, the sound of the Aune S17 Pro is warm and detailed, with performance reaching a very low level of distortion.

Efficient heat dissipation and clean power supply

A three-dimensional structure consisting of internal heat sinks, an imposing plate and the chassis forms a highly efficient complete cooling system guaranteeing the stability of the Class A amplifier stage. A 50W toroidal transformer coupled to 19200uF array capacitors feeds the digital and analog sections independently to limit any interference on the analog section. These features enable the S17 Pro to be powerful while delivering a rich, clear sound.

Aucun avis sur le S17 Pro d'Aune ?. Je suis étonné ! Après 1 semaine d'utilisation, je ne peux que me réjouir de l'avoir choisi. J'écoute beaucoup au casque, j'ai donc acheté et essayé pas mal de combinaisons d'appareils, ampli-casques ou amplis intégrés, Topping, Fiio, Smsl, Rega, Marantz, Pioneer, AD 18 qui fonctionnaient assez bien avec mon Hifiman et mon Sennheiser. Pourtant l'Aune m'a fait franchir un gap et je suis encore sous l'effet "waou" après une vingtaine d'heures.
Le S17 est en classe A, il lui faut être à bonne température avant de totalement s'exprimer (30 mn), la température est d'ailleurs indiquée sur l'écran. On peut choisir le courant de repos et le gain.
L'Aune a de la matière, de la densité tout en étant transparent et détaillé. Je peux suivre les lignes de basse comme jamais auparavant, les voix sont très présentes et suaves, les aigus sont présents, sans agressivité ou sans sibilance. Mais, la qualité à laquelle je suis le plus sensible (et mon Hifiman aussi), est la séparation des instruments, l'espace que prend la musique, l'image, certainement fausse en réalité, mais tellement plaisante pour ceux qui aiment écouter au casque.
Trop de qualités pour être vrai diront certains ... oui, le temps me fera sans doute modifier une partie de mon appréciation. Mais pour l'instant, je profite de ma "lune de miel avec cet appareil" et ce, j'espère, pour un long moment.

Nb 1 : pour éviter de trop monter en température, mieux vaut surélever l'appareil. Je l'ai fait en le positionnant sur 4 petites équerres de bricolage placées en dessous, en position horizontale.
Nb 2: la pile de télécommande est fournie, contrairement à la description. (j'ai fait 15 kms pour rien!).
Nb3 : Commande passée un mercredi matin et reçue le vendredi matin à 700 kms d'Audiophonics ... chapeau !
