Mids : sweet, fluid and musical. The strength of this valve lies precisely in the mid range , where voices and acoustic instruments are returned with warmth, naturalness and transparency . The output is emotional but measured, ideal for those seeking involvement and timbre authenticity.

Highs : clear, bright and controlled. The high range is well extended, with an airy and harsh-free detail. The brightness is always elegant, with well-resolved micro-information and a fine grain that contributes to the overall coherence of the listening.

Dynamics : wide, precise and well distributed. The long plate structure allows for natural management of micro-dynamics , with a prompt but fluid reactivity, capable of accompanying every variation with delicacy and strength at the same time.

Soundstage : wide, immersive and three-dimensional. The stereo scene is stable and well-layered, with an excellent sense of depth and spatiality. The coherent behavior between the quartet valves ensures operational symmetry and timbre homogeneity , enhancing dual mono and balanced configurations.
