Duelund cast Pio Hybrid Copper/Silver or Rs series with Silver Bypass PIO

I am glad to have found this thread and would like to chime in with a question. I have just learnt to upgrade capacitors. I recently replaced the stock caps with a pair of Audyn True Copper Max caps to my Line Magnetic 518ia and had great result. And I just placed an order this past Friday at PartsConnexion for a couple Jupiter Copper Foil caps for the crossovers. 

Since I read this thread, I wonder if I should replace the Audyn caps with the Jupiter caps in my amp. Can someone please give me your advice?

I thank Zipost for starting the thread and thank all for sharing your experience. 

Happy listening! ... and experimenting :)

I thank you for your inputs. The descriptions are accurate. For now, the Audyn Copper Max caps will stay in my amp for they sound much better than the stock caps and I only have had them a few weeks. I will keep the Jupiter Copper Foil caps on my upgrade list. 

FYI, I placed an order of some Jupiter Copper Foil caps for my speakers at PartsConnexion couple days ago and had 25% discount.

Happy listening!

hificollective in UK carries Duelund, so you might want to check with them. They ship fast, too. I got my caps in one day with expedited shipping and did not pay a lot extra.

Hope you can find what you want there.
