FWIW to the cohort unfamiliar with NORDOST cables:
Ignoring improved insulation as one goes up, their models line, the cables are grouped and sold by the numbers of individual wrapped ferrules and diameter thickness of the thin speaker gauge in the ferrule.
I’ve owned low end LEIF class via PURPLE FLAIR speaker cables, and medium grade NORSE class via FREY full loom .I’ve auditioned them many times but not personally owned REFERENCE class VALHALLAs or ODINs
NOTE: There is a reason why the largest cohort of of the audio expo exhibitors select NORDOST VALHALLA or ODIN to showcase their products (along with CARDAS CLEAR / CLEAR BEYOND ). They are the top models respectively that sound .spectacular….
Conversely, the NORDOST bottom tier LEIF class options… are an expensive choicecto buy and not the greatest contender in their pricepoint = not so great choice that can be easily bested by peers.
MY POINT
To properly assess your new DYNAMIQUES as an upgrade contender how about doing a proper A-B bake-off against the NORDOST VALHALLAs as a better measure of NORDOST audio performance capabilities of an Ag coated over Cu contender. They have the overall improved number of ferrules and thus a thicker overall mass .
