\" The choice of this valve is an excellent choice, if you buy it you are sure to have made a large purchase. It is definitely a relief those considered definitve, obviously depending of your preferences.That because It is a brilliant and fast tube; it shows the treble area very well balanced even if they are not to be very exetended but very much audiophile. The voices turn out to be very accurate but without hissing and with Live presence.It has a 3D soundstage quite definitely with an advanced position. The locations of the instruments on the soundstage is perfect..the middle tone is slightly emphasized but never annoying ... indeed. The low is well-extended, brilliant and powerful.\"
