It really depends on the sound that you prefer. You need to listen to a few.
Help me find a suitable speaker cable for my all McIntosh system
I have only auditioned AQ speaker cables and the ones I like cost too much. I would like to keep my purchase under 5500 or much less if possible. My speakers are BW 800d3. Silver seams to make a bigger difference than all copper IMO w/AQ cables.
