How would you compare Acoustic Zen to Nordost

I would like to know if anybody has done any comparisons between Acoustic Zen Silver Reference MK2 and Nordost Quatrofils with either termination.I use Quatrofils between my Theta Casablanca II and my Krell KAV-1500 Amp.I use Quatrofils on all my other components also.Which cable sounds better and why.I have Aerial speakers and listen to about 30% DVD and 70% music.I use Nordost SPM Speaker Wires;bi-wired.I'm 54 years old and I have a slight loss in the ability to hear some of the high tones;so maybe a brighter all silver cable would be better than Silver Coated Copper.Thanks Ambrose.
