First they are Duelund Capacitors and they do offer great performance at a price though. I assume that you want to use them in the crossover for the tweeter requiring either one or two capacitors depending on topology, that can get very expensive, most likely costing many times that of the tweeter it self.
Theres a very good capacitor test Here as you can read the CAST gets absolutely top grade by the guy performing the test, i.e. it is his opinion.
I do use the Duelund VSF capacitors in some of my Superleague speaker models and have on customers request upgraded them to the CAST model in some.
As with anything theres a diminishing return on costs once a certain level is reached and while the CAST are excellent capacitors the VSF models are very good too, other favorites of mine includes the Jupiter HT Beeswax caps and the Jantzen Superior and Silver Z capacitors.
Do they change the sound drastically, no, its more like a spice for lack of a better word, they all flavor a little different.
Good Listening
