DESCRIPTIF CONFORME
Belle scene sonore, belles définition, belle musicalité, bref dans la lignée de qualité d’écoute de ce fabricant et comme toujours à prix imbattable. Privilégié au Genalex Gold Lion qui est déjà une très belle référence. Installé sur mon préamplificateur Aesthetix, les tubes livrés fonctionnent parfaitement (4éme série de tube commandée chez Audiophonics et parfait fonctionnement pas comme chez TAD). Appairage pas nécessaire pour un préamplificateur, la balance est respectée. Donc sans hésitation.
