Take a look at some the the less expensive Zu Cable interconnects. Kimber PBJ is popular. One fo the cheapest that still performs decent is the Straight Wire Chorus ($39 a meter brand new at AudioAdvisor.com). The SW Chorus is also Purple, if color matters to her (WAF in training, Ha!!).
I really like the MAS cables made by Stu Wein at Audioparts@AOL.COM the best. He sells his Black interconnect for about $50 meter pair. It is more neutral and analog than most other cables I have tried under $100. His Blue cable is pretty decent for $30 a meter (I would pick the Blue over the Chorus).
An inexpensive Toslink may mean a trip to Best Buy??
