Pros - Clarity, build quality, looks, great even before burn in.
Cons - Price, size
This is one of the last things you need to upgrade when your making your portable rig. Vs the fiio L9 this lod cable was a big step up. The first thing that will hit you is the increase in volume and clarity. You will find better imaging and the feeling of your headphones opening up or becoming unveiled. The down side is that since its not right angled like the L9 it will make your portable rig longer. I personal love the way it looks and would reccomend it to anyone who has expensive gear using not so good cables.
