Zipost, 
I'd say that if you are committed to this region of top tier capacitors then get the CAST copper rather than the tinned copper version.  As Grannyring wrote,  these are the ones we've both have used with exceptional results.

No reason to replace those wonderful Audyn caps as they are also very, very good! 
Chumsusi....Audyn Max has a beautiful midrange very sexy type of midrange ( i still miss the midrange).   The highs shimmer exceptionally classy.  Bass is neutral, but can be better!    But to me the Copper Max has a very neutral organic type of sound.  Some people might like it other thinks it's a thin sounding cap.  To me i think it's a neutral sounding cap.  

I had great success using Max as a coupling cap for my cd player.   I wish it has the thickness in sound, a little bit more meatier.  I think that has to do with the dielectric/material and type of insulation.   This is where Duelund & Jupiter outclass other type of caps, it makes the Biggest Difference.   This is the reason why i am going to replace it with either the Duelund or Jupiter to get that meatier/thickness sound. 
I found the Jupiter copper cap to have better bass impact compared to Duelund cap as an FYI. Again, I found this to be true in high voltage useage, not crossovers. In terms of thinness, both the Jupiter and Duelund CAST have meat on the bones body for sure. Both have great in this regard. 
PartsConnexion is all out of the Duelund Cast Copper.   I wanted to order a pair but no luck, kind of wish they had more stock.   Anyone or somehow can locate me a pair of the cast copper series 1.0-1.5uf 450v.  Much appreciated!
