Curious How These Nordost Speaker Cables Do What They Do

For a day and a half I’ve been listening to Nordost Red Dawn Rev.II cables in my system(Quad VA-One and Dynaudio Excite X14),courtesy of a friend who is in turn demo’ing some ungodly expensive upgrade...My reference are the Acoustic Zen Epoch..What these cables have brought to my system are:
The first thing I noticed is the music seems to come easier,ie:a touch louder than normal at low levels and it’s so clean I find I’m listening louder..
wider,deeper,and sharper defined imaging and staging...deeper,better defined and tonally richer bass...increased low level detail retrieval...a treble that is not as easy on the ears but seems better defined,almost sharp and I can see where some systems could move way to far into bright with these cables...
So I attribute the cleaner/sharper tone to the addition of high purity silver to the cable but I wonder what it is about the materials and construction that allow the bass,imaging and staging changes and especially the ease which music seems to come now?Any comments(from those who have found cables do matter)and NOT from those who believe they are snake oil PLEASE!!!
