sonic signature of Pure Note Paragon Question

I just got a set of cables tonite , brand new. This is a first impression but i am alarmed . The entire system is Paragon . They are dry , lacking in air , have little bass and have little timbral richness. They seem to be hyper accurate however with good depth and focus. For owners who have had them a for some time , what characteristics will change and how will they end up changing / sounding ? Thanks !!
