Interesting comments on the Duelund requiring you to set the treble tone control to -2. That corresponds to my findings exactly. I found them slightly tipped in the upper mids/low highs and I don't have tone controls. Over time this very slight emphasis was not as musical to my ears, in my system, as the Jupiter caps.
I do suffer tinnitus and I require my highs and upper mids to be smooth and not even the slightest bit emphasized. The dead quiet and ruler flat response of the Jupiter caps really have me smiling.
The noise they remove also helps my tinnitus.
I also find the Jupiter caps soar higher in the highs with more air. Important not to confuse this with a slight emphasis in the highs as they are not the same.
I found this difference in electronics and cannot speak as expertly on speaker use.
I try to post these details so readers get a sense of the flavor differences as one one cap is not better than the other in all conditions and for all needs.
I can say this. Jupiter copper foil caps burried in Reptisand filled crossover boxes are astoundingly quiet and absent of noise. Shockingly so.
