What capacitor would you use to upgrade Wharfedale Linton 85th Anniversary?

I’m going to swap out the generic 6.8uF cap on the tweeter side of the crossover. Wharfedale was very supportive and sent a schematic.

Note: If you have opinions that gear shouldn’t be modified I’m not interested. I can easily swap things in and out seamlessly. Also, my view is that manufacturers have much slimmer margins than we might think. Having built stuff and modified stuff, we experience first hand the choices that engineers and bean counters must make. My sense is that the Linton can be elevated further because of this. And, capacitor swaps can be more influential (and yes, good or bad) than swapping power cords/cables.

The Linton doesn’t do anything wrong. Some might say it’s a sinner of omission? It’s overall smooth, non-fatiguing, and can really keep singing as you push power at it. I wouldn’t mind a touch more air and definition on top--without losing the smoothness.

• Jantzen Superior Z-Caps?
  
• Clarity?
  
• Obligato? Man, these are reasonably priced.
  
• Auricap? Another smooth, reasonably priced cap.
  
• I’d love to try Audyn True Copper Max or VCAPs but that would be pretty pricey.
  

I’d prefer not to break the bank, which is the problem. I haven’t set a budget or priority for this project. 6.8uF values can get very pricey. So, I suppose it should be kept to less than or equal to $100 per cap. I could be persuaded to do more. :)

Any thoughts?

Calling Erik Squires! @eriksquires ! I know you have some intel here Sir!

All suggestions on caps welcome!

Thanks all!
