For your use I would stick with the copper CAST. They are wonderful. I am not sure you need to add the bypass silver cap to be honest. Sometimes resolution can be taken too far and long term listenability can suffer. Many recordings are less than perfect 😁
I agree with EriK on the copper Duelund CAST and even the RS as my go to choice. Also, sometimes adding a bypass cap in high voltage electronic applications gives a strange sort of result. Sometimes it can be good and sometimes not as good. Crap shoot and with this kind of money I would not take the risk. Stick with one high quality cap and you may well be better off.
Lastly, don’t discount the Jupiter copper foil cap. I actually like it every bit as much as Duelund copper CAST and they cost far less. Sonic Craft has great prices on these wonderful caps. The Humble Audio site rates the Duelund caps a little higher, but remember these were only tested in low voltage crossover networks, not electronics for coupling. I have compared both in coupling positions and the Jupiter copper foil caps were wonderful. The CAST copper were also wonderful. The Duelund is quieter with a dead silent background. They also had a very slight emphasis in the upper midrange. The Jupiter caps had more air, improved Micro details, and were more even handed through the upper mids.
Food for thought!

Curious as to why the builder said avoid PIO caps? Yes the Jensen caps are warm and a tad slow, but nice overall. Not all PIO caps sound the same however. If you love speed, resolution and air, then go for CAST hybrid! If that is what you are shooting for you will get it with the hybrid from Duelund.
I have compared Jupiter copper foil directly to Duelund copper CAST only. I compared in the same gear and in the same position so I have a good handle on the sonic differences. I did this in a tube dac, tube preamp, and tube amp coupling positions. My comments in the previous post should help you decide.
If money is no object and you want ultimate resolution, speed, detail, air etc... then the Hybrid is your best choice. All Duelund caps have this in common as well as a dead quiet background. They, like all PIO style caps, sound very real and less plastic or artificial. The Jupiter caps share this real sound and avoid sounding electronic. Duelund caps sound a tad richer then Jupiter. But I must point this fact out. Duelund CAST copper caps do highlight the upper mids and that in the end forced me to go for the Jupiters which sounded more even handed throughout the sound spectrum. My ears are very sensitive to upper mids due to my tinnitus. Some will prefer this upper mids presence and you must know your preferences. On good to great recordings the slight emphasis on the upper mids is a nice thing. However on less quality recordings it can become a tad irritating. Also, what kind of music you listen too is also important. |
This is the cap Charles and I used and liked. All you would need with no additional bypass cap.
Duelund cast PIO CU Copper series
They are expensive. Go ahead and email them saying you would like to splurge on these but need help and ask if they could offer you a 15-20% discount. They have for me in the part on these mega expensive caps. |
@chumsusi
No reason to replace those wonderful Audyn caps as they are also very, very good! |
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. |
Why not use the silver bypass cap on the better Jupiter foil cap for the best possible combo?
|
To clarify, your question on the Duelund hybrid cap relates to my post in that they are made using the Duelund CAST copper cap with a silver foil bypass cap.....the same cap that can be purchased separately now. The cap I posted on above.
So yes I am confident the hybrid Duelund cap would be simply wonderful sounding. |
I have to tell you I do not believe in bypass caps placed on film caps. Yes, on electrolytic caps in the power supply. Usually bypassing perfectly good film caps sounds kind of phasey and odd.
Well, forget everything I just said. Why? Because these new Duelund Silver foil bypass caps are like magic. I added them to a set of .47uf Jupiter foil output caps in my Int amp and simply am overwhelmed with the improvement. My experience, in electronics, is crazy positive with these glorious sliver bypass caps. Glorious.
These would be so special as bypass caps on tweeter and midrange caps in a crossover, the output of Class D amps, coupling positions in tube gear, output on dacs....etc....
Yes, my experience has been so positive. |
No worries on the oil. I am not aware of any such issues in real life usage. Oil impregnated caps have been sold for decades. This would be especially true for crossover usage where there are no heat issues to worry about. |
Very nice. You have some very high quality boards that will help make your speaker sound beautiful. Did you make the inductors or were they made for you? Nice! |
You made a good decision sticking with the heavy gauge solid core wound over foil. You will love the results. What are you using for internal wire. Looks like Duelund copper stranded? Thoughts of placing the crossover outboard? Very good for Sonics.
|
Nice looking speakers. Look to have great build quality.
|
Yes it will. Jupiter copper foil will be even better with that wonderful Duelund bypass cap. |
I certainly do think so. I have compared the Duelund CAST to the Jupiter and I actually like the Jupiter even more. It is a wonderful sounding cap. |
They are nice, but not my particular cup of tea. Just a tad too thin sounding vs Juputer or Duelund CAST. |
I don’t know it, sorry. What do your hear and want to improve? |
The newer tin plated copper. |
Erik is right about the Mundorf cap. If you want more air with a more natural and real tone, then Jupiter copper foil is your best bet. They are not cheap however.
|
Never heard it. Sorry. I would use a nice solid core wire in silk or cotton on that tweeter. Jupiter makes nice solid core silver and copper wires in cotton and silk.
Another great option, not in cotton or silk however, is the Neotech stranded silver with gold plating. Get the heaviest gauge which I think is 23 or 24 from Parts Connextion. This wire sounds absolutely wonderful, but is not cheap. Much better than the Mundorf silver/gold wire based on my experience.
Yes I would go with the Jupiter copper foil cap for sure. If you want even more air, articulation, space, and realism add a pure silver foil Duelund bypass cap .01uf. This particular combo works so well together. I have found the net result (combo) to be the finest cap available at any price. |
This was just for the tweeter per your note? I never liked silver plated copper wire. All of it I tried was too bright and aggressive for my likes. Confused about your needs now. |
I wire my speaker projects with Duelund stranded copper in cotton. I use 20 gauge on tweeters, 16 gauge on mids, and 12 gauge on the bass. Love it. My favorite wire of all time. I also like Jupiter solid core copper in cotton on tweeters and mids. |
I have not, but I have used Vcaps before and like I said earlier they are just not natural and smooth enough for me. I do not believe in bypassing caps in the signal path usually as it can lead to a nervous and phasey sort of sound. However, the combo I mention above is a special exception and works marvelously. Other combos are tricky and the results may or may not be good. Crap shoot. I have done due dilligence on the Duelund silver foil bypass cap and Jupiter copper foil combo and all is great. |
