i just want to kindly thanks for all who responded to my questions.    Your advise and input helps alot and will make me understand more about caps, and let me decide which will works best with my application.    Your info are greatly appreciated!

grannyring...

the Jupiter copper/oil wax,  I like the fact that Jupiter doesn't use oil but wax instead.  I find that Oil in cap ( Jenson copper oil) was a bit slow for me.  Here is my dilemma!!  I am trying to find the right cap for my tube cd player.    The design is base on a triode output tubes, the coupling cap calls for a 1.5uf, 450v.   I spoke with the Manufacturer, he recommended that i do not use paper/oil.   

So my question:  Should i stick with the Duelund Rs series or Jupiter copper/wax?? 
Or just ignore his info and buy the top of the line Duelund cast PIO hybrid!  





I made up my mind, I will be placing an order for the Duelund cast at PartsConnexion. My questions here is that they make so much series, just mindboggling.

Duelund cast Pio Tinned Copper series
Duelund cast PIO CU Copper series
Duelund cast PIO copper/silver Cu/Ag Hybrid
Duelund cast PIO Ag silver series


Tinned Copper series vs copper series... what difference does this make by adding tin? So much good stuff to choose from. Please advise??


I did more digging/researching into the Duelund Series:

Duelund Cast Copper/Silver Hybrid =VSF cast series + Bypass cap .01 PIO silver series put together in one cap.

if that is the case:

Then the RS series + a Bypass cap .01 PIO silver series be cheaper in price or equal in proformance to the Duelund Hybrid series.  What your take on this?  



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. 
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!  

I got a chance to buy both the Jupiter Copper Wax & Duelund Rs Series w/ the .01 Silver Bypass. I want to give my feedback in regards to the two caps.

I like to say thanks to Chris at Jupiter for giving me his utmost time answering my questions and letting me purchase the Jupiter Copper/Wax caps.   He was nice enough for a one time courtesy sample price on these caps.

Jupiter Copper Foil Wax Impregnated:

These caps i would estimate has around 100-150 hrs on them.   I notice it got better everytime i start listening to them. I have to say, this is the first time i encounter a cap that has copper impregnated in Wax. Right out of the box i noticed the design, packaging and the look of the cap is amazing ( sturdy and has weight compare to other caps) it shows that they do care when you spend money on these things. The Jupiter Copper Foil is a detail ( shimmers beautifully) has good transient, has airy mids ( very sexy mids) and tight bass.    Bass is much deeper and tighter.   You can't really say anything bad about the cap. But......

Duelund Rs Copper Wax series w/silver bypass:
just the cap without no bypass, it lacks in detail, midrange is exceptable, but suffer on bass (bass is muddy).  If you compare it to the Jupiter Copper Foil it will Not Compete.  It looses in all categories!  But With the silver bypass,  it's exceptionally good.   It brings the cap to another level!! The high seems to be alot better, midrange is beautiful, bass is quite good.  Blackness is the strong point in the Duelund Rs series w/bypass cap and noise level is much lowered. One thing that stands out the most is the realisim and soul, the Duelund to me is exceptionally good in this category.  The sound is extremely thick and meatier compare to the Juipter copper foil.

In all i would pick the Duelund Rs series with Silver bypass for the output coupling on my cd player. One thing that i did not like about the Jupiter cap, it lack the heart and sole ( very analytical). The Jupiter Cap wasn't musical It's very thin sounding cap compare to the Duelund Rs series with .01 silver bypass.







Grannyring...the duelund silver foil .01uf bypass is Amazing.   I think it's one of the best bypass cap that works wonder in any cap.   They make a huge differences in Any cap! 

George.... thanks for the info.

let say if i did use the hybrid duelund 1.0uf 630v for the coupling signal, which is basically a silver foil .01uf cap bypass with the cast copper cap?  So this will not work?  What is the differences between de coupling or coupling?  Can you Please educate me on this? 




Excellent point!  I am with you on this, longevity might be the Biggest issues for the Duelund caps or any other caps that has the oil impregnated in them.   
I would not think the Rs is comparable with the Jupiter copper series.   The cast duelund to me sounds better than the jupiter copper series.   Has more organic, lively and romantic sounding.  
pumpwheel... v-cap Cutf works well in a bypass for power supply.  if you want transient and dynamics i strongly recommend on the power supply section.  For signals, the v-cap is on the bright side, it can be tooo detail from my experience.  The duelund silver bypass is very nice.
