What interconnects work best with Audio Research?

Then get yourself Cardas or Kubala Sosna wires. They are both on the warm side and have a lot of texture.

Agree, CARDAS is the brand for you. Be extra carful about used Cardas.. they have had a problem with fakes! Make certain you buy from a retail seller, or (used) from folks who have a long and solid reputation who are 'original owners' and can proove it.
(Few other cables have the 'look perfect'forgery problem Cardas has)

Thanks, which of the Cardas line up should I use.......
