The “Silver” (Silver and Ultra Silver) has been designed for those who love detail. As has already been commented on, with the Ultra silver the top end is extraordinarily detailed without any harshness.
While the “Black range” (Black, Ultra Black and Black Diamond) could be categorised as neutral/ natural the “Silver” would lean more to neutral, detail and extension. The Silver performance sits beyond Black for very good reasons that you will hear.
"I then listened to the silvers and Wow, what a change. Not so much as baby step, more quantum leap. The silvers were just more musical and made me tap my feet that much harder. I hear musical instruments that I had not heard before, the separation between the musical instruments and vocals was that much clearer, the sound of the instruments that much crisper. Overall it just lifted the system to a new level - something I was skeptical of before hearing them".
