Well, I am not sure of your budget, so I will make two suggestions. (FYI, I have no idea if these will work with SET amps or not, but I can not think of a reason why they wouldn't. They certainly work great with our Lamm Hybrids.)
One, if cost is no object, the Nordost Valhallas.
Two, if cost is a factor, the Audience Au24s.
I own the later cables, and my friend owns the former. I have heard both in his system, as he sold me his Au24s in order to upgrade to the Valhallas. The Au24s were really pretty close to the Valhallas in all aspects. The treble in particular sounded great with both cables, with lots of decay and not a trace of brightness.
(But if only the best will do, go with the Valhallas! They do sound just a little bit better, At 4 times the cost, they should much better, but that old law of diminishing returns keeps popping its head up!)
