Après 5 jours d'utilisation, je suis très satisfait de l'opendrc-Di. Je l'utilise pour faire la correction de ma pièce quand je regarde la télévision ou un Blu-ray. Les filtres sont calculés grâce au logiciel Acourate. le résultat sonore correspond à mes attentes, voix et grave plus nette, disparition des résonances désagréables. Bref dans ma pièce à l'acoustique très moyenne l'apport positif du Opendrc est incontestable.

Malgré cela je ne met que 4 étoiles car il y a des défauts de finition. Par exemple, les clapets des prises optiques ne se referment pas.

La livraison est rapide.
