Parasites
Exactement le meme parcours que Stephane, des gros parasites, souffles et meme un beat étrange. Testé avec plusieurs alim, impossible de trouver la cause.

Super SAV, très cordial et réactif. J'ai renvoyé le produit.

Médiocre.
L'ampli est plutôt bien construit, solide, et semble de bonne facture.
Mais à l'usage (et sans être un puriste, souffle acceptable), des bruits parasites importants en sortie et des ronflements qui s'entendent notamment à faible volume lorsque la musique joue. Après de nombreux tests ainsi que des mesures à l'oscilloscope, difficile d'en trouver l'origine sans schéma électrique de la carte (plutôt liés au secteur Alim dans l’ampli plutôt qu’au secteur Amplification…)
J’ai retourné au SAV (par ailleurs très cordial, merci), ils ont testé avec un neuf du stock, mais constate les mêmes caractéristiques (« léger souffle et petit train de parasites »).
Je vais tenter ma chance vers une autre marque.

Bon produit
Ampli de bonne facture, un son plutôt dynamique et de puissance correcte, attention toutefois que pour les personnes ayant l'habitude de parler en Watts RMS on est plus proche des 10-15W RMS propres (sans disto). En aucun cas 50W dans de bonnes condition (c'est tout de même honorable pour un si petit chip.). Très bon rendement, ne chauffe absolument pas, même après 1h à pleine puissance. Le bluetooth se connecte rapidement sans aucun problème et le son par celui-ci est très bon. (acheté avec le module batterie pour 3 cell lithium et le pack de câbles) le fonctionnement sur batterie est efficace, plusieurs heures à bon volume avant la décharge.
