I have this new cable arrived couples of days ago, the Plussound Silver+ has done amazing things to Raven sound. With burn in Raven bass response and overall sound will improve, but still doesn't suit my taste for my music library, the overall sound with stock cable still a bit too warm and thick, the treble needs a bit more air.
The Plussound Silver+ give me exactly what I want with Raven and more, the staging expand in all directions, imaging also improve. I no longer tips rolling anymore I am back using stock tips with my usual size. I know cables effect on the sound of IEM is debatable but I think Silver+ effect on Raven sound is the most noticeable from my personal experiences with Cables & IEM pair up.
