Try the Tara Labs Air 1 or the ISM The 3 or ISM The 2. These are very smooth cables and do not sacrifice detail. The are very neutral sounding with great isolation from noise. Probably one of the most overlooked cables around. Sumiko uses Tara in their lab for their equipment including the REL sub. They don't add the slight coloration of the Cardas cables but give you an open look into the soundstage.
