An ideal cable from a visual/low profile standpoint would be 47labs OTA cable kit. This cable costs $600 for 50meters of raw cable. Hence, this would provide 12.5 meters of stereo cable. If you can use slightly less length on the speaker cable, then the kit allows you to make three sets of interconnects as well, in a very interesting way - using bare wire for the complete connection (no metal plugs etc). The cable is very good (check out the audiogon threads on it). It is also only .4 of a milimeter thick!!, but with plastic outside is a little thicker, but still about as unnoticeable as a cable can be. Some threads say it may be the best cable bar none. I own the cable and IMHO it is not even near the best there is but it is very cost effective. Good luck.
