KR audio kt88
je n'ai pas terminé le rodage, je ne suis qu'à 60 heures à volume modéré, mais je suis impressionné par le gain énorme par rapport aux KT120 tungsol puis aux ps'avane KT88 markII (définition des timbres, séparation des instruments, graves bien mieux définis, perception des différences de niveaux et qualités d'enregistrement); à mon sens, du vrai très haut de gamme; l'investissement ( conséquent, j'en conviens) en vaut la peine.
