Excellent produit
J'ai utilisé 2 modules UCD400HG pour remplacer les 2 modules identiques de mon Micromega AS400 qui donnaient des signes de faiblesse après 12 ans d'utilisation.
Sans surprise je retrouve la sonorité originelle de mon AS400, c.a.d un son neutre, détaillé, transparent et dynamique. Ces modules permettent d'avoir de vraies basses sur des enceintes difficiles à driver et gourmandes en courant, telles mes Martin Logan Theos dont l'impédance peut tomber à 0,7 ohm.
Avec une bonne alim, un bon préampli et un bon refroidissement (c'est de la classe D mais 400 W cela chauffe !), ces modules peuvent donner beaucoup pour un prix très raisonnable. Seuls petits bémols : la diode bleue d'un des modules s'éteint lorsque l'ampli est chaud alors que le module semble parfaitement fonctionner, et puis je m'aperçois que j'ai payé chaque modules 6 € plus cher que leur prix actuel.
