What is your budget for interconnects? There is a guy on eBay Stu Wein, screen name and eMail email@example.com who owned Music and Sound "MAS". His digital cable use to come standard with the Wadia DAC and the similar interconnects got favorable reviews in Stereophile at the time. Well he still makes the cables in his spare time and auctions them on eBay. He will also sell them direct if you eMail him. His best MAS Silver Grey cable he will selll for about $85 a meter pair. I have a pair and they are as good as others costing up to $300. He also has his MAS Silver Black which he will sell for about $50 per meter pair. They sound as good to me as cables around $150 to $200 like Nordost Blue Heaven and Van Den Hul D102 Mk3. Stu also make a couple very nice power cords; one for around $50, the other $75 which sold as the MAS Audio One.
If you want a commerically available cable the Siltech "entry level" ST-18G3 is quite nice. I have two pairs; one really makes my Tuner sing.
