they sound great and are very resonable in price
check them out on our showcase on audiogon
hosa does a toslink cable you can likely oick up at a music store(mars etc.) for $9-$15. when i had toslink in the system i prefereed this a lot more than kimber's toslink.(it was more detailed/easier on the ear. the kimber was a bit more 'lively' though.)
i'm sure your sister is going to have fun whatever happems with here adventures in cable land. :)
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??
Based on an earlier recommendation by Sugarbrie, I bought a pair of MAS cables from Stu Wein, Audioparts@aol.com. I got a somewhat more expensive model, MAS Grey, for $80 to use with a Cambridge Audio D500 CD player, and have been very pleased. They made a clearly audible improvement in the sound of my system. The MAS Blue cables at $30 or the MAS Black cables at $50 would probably be a good choice for your sister, since she has spent less than $200 on the CD changer and DAC.
Some people just don't get it. It's matter of personal preferences. My sister loves travelling more than audio. She travels twice a year. At this very moment she is on a Caribbean cruise w/ my mother and she paid for the whole thing. She'd rather use Radio Shack interconnects for her cassette deck and have Sean cook them...
Her system is still going to be better than most women's, anyway.
