The magic of the Cast caps is undoubtedly in the oil. I’ve used 600v Duelund Cast caps in an amp and I know the beautiful sound they convey until the oil leaks.

Oil leaks is one issue. What about the shelf life of the oil? Does oil degrade over time? Does the Duelund magic deteriorate over time?

V-Cap CuTF and Jupiter Copper caps won’t have those issues and are my preferred caps to use.
Jupiter caps are excellent and are the best "bang for your buck" brand. The Flatstacked series which I'm familiar with has a natural tonality and open soundstage.
