JAM by Duelund

I have not try the Jam caps yet but by their look it's either made by F&T or Jenson.  Not an in house like most of the Series they made.  I can say they are cutting cost and going to a more productive and cheaper way to produce their caps.  This is just my honest opinion!  

I just ordered the Jam caps after speaking with Frederik at Duelund
He said they are made just like the cast, except the cast use further resonance 
And high compression paper case which is much more labor intensive then the Aluminum  and better sounding still.which is made in house  ,most likely on a Jensen machine but to 
A much higher standard. The Tinned Copper is shared by only the Jam,and Cast.
He said it is noticsbly better then the older Alexander,and the paper in oil dielectric allows that deep rich Tone ,where the tin allows the top end to shimmer and Copper gives it depth of detail. My friend in the U.K has used them and he said 400 hours to fully develop but a true bargain. These are currently introductory 
Priced . P.s they have the .01 silver paper oil bypass caps which my brother put 4 in his preamp, for $100 each he said it was a bargain for gains in  resolution alone and very natural no silver brightness what So ever.

Sounds great Audioman, please come back and tell us how it goes : )

Enjoy the tunes

Any more feedback on JAM caps?

@audioman58 You've recommended Arizona Cactus + Jupiter Copper combination which is potentially better than Duelund. Is the cactus + Jupiter combination better than JAM in your opinion?

I personally like Jupiter copper foils as much as Duelund CAST and more than the Duelund RS. The JAM is not as good as RS .... well they are under the RS in the Duelund Line. I would go with 100% Jupiter Copper foils.  This is especially true in electronics.  Not sure if these are for crossovers or elsewhere?
