Impressionnant pour le prix
Comment dire...mes préjugés sur les amplificateur en classe D sont tombés...exceptionnel de transparence,sur des enceintes de rendement correcte (92 db) aucun tassement de dynamique ni de saturation même à niveau sonore déraisonnable
Comment vous faites pour moins de 300 euros ??
Petit aparté : je le trouve plus équilibré, moins brillant dans l'aigu que le AO 200 mk2
DAC INTÉGRÉ de qualité tres moyenne, mérite un dac externe

Je l'ai acheté ici il y a quelques mois. Incroyable. Rapport qualité prix bousculant beaucoup de references beaucoup, mais alors beaucoup plus cher. A acheter sans retenu.

It is an overall excellent device (SMSL AO300), well thought out with a wide range of connection options to the source and end components of the apparatus.
In terms of sound, I am satisfied with its clean, natural sound on both analog and digital connections. Speakers used are B&W CDM-1 + Dali SW-8; on the headphone output there is an excellent combination with 1MORE Triple Driver Over-Ear headphones (slight modification - removal of 2/3 layers of foam above the drivers).
I wanted (ordered) a black version, a version with a silver front panel arrived. . . :-)

Exeptionnel
Pour cette commande tout s'est bien passé et rapidement, et j'ai enfin pu écouter cet SMSL AO300. C'est tout simplement exceptionnel. J'avais déjà gouté un ampli numérique avec le V200 de I AM D (pas tout jeune, mais déjà très bon). Là je suis tombé dans une autre dimension d'écoute, impressionnant.
Le seul regret que l'on pourrait avoir, c'est au niveau de la documentation qui pourrait un peu expliquer les différents filtres et EQ. Si vous avez quelques écrits sur ce sujet, merci de les faire connaitre.
Encore bravo pour le produit et le service.

Excellent rapport qualité prix
L'AO300 n'est certes pas l'électronique la plus chantante que j'aie eu entre les mains. Le son est relativement froid et piquant, le haut du spectre n'est pas doux, les médiums paraissent clairement moins naturels et plus décharnés que mon système secondaire : gusrard r26 / aune s17 pro / topping la90d. Mais peut on attendre une telle performance d'une électronique qui coûte 10 fois moins cher ? Évidemment non, en tout cas pas pour l'instant ! Pour autant, les filtres du dsp sont très efficaces (l'égalisation fonctionne bien), les options sont nombreuses, cet appareil fait tout. A partir de là, pour le tarif, c'est un objet excellent.
