Moryoga,
There can be a number of reasons why Basis used someone else's cables at a show and not all of the reasons involve sonics. For example, exhibitors often team up to defray cost. I've been at shows where the horse trading and last minute arrangements/deals are made because certain equipment fails to arrive on time or is not working when it arrives. You can find really strange bedfellows resulting from such happenstance. Some manufacturers show up with a lot of extra gear for big shows, like CES, hoping to get as many rooms as possible to have their stuff. Cables are the sort of gear that is easy to pack a lot of extras for this purpose.
