Excellent rapport qualité/prix
Tubes installés sur un ampli Fezz Audio Titania en remplacement de GENALEX GOLD LION. Tout le spectre sonore passe très bien, très bon équilibre et j'ai surtout retrouvé le grave qui avait disparu avec les GOLD LION, c'est le jour et la nuit. Le tout pour un prix très compétitif.
