A cable that sounds very good and doesn't break the bank is the DH Labs custom D-110 made by Moon Audio. I've compared it to the Kimber Illuminations Orchid and it it very hard to tell the cables apart. (connected between a Wadia 20 and MSB Platinum Plus) There are various reports stating that there is an ideal length for digital cables. Kimber states that a 1.5m Orchid is the best sounding length. I compared 1m cables, you may want to consider a 1.5m D-110. You'll still be under a $100 with shipping.
