Dueland CAST PIO

In my vintage speakers, the Duelund CAST was the best sounding of many, many caps I tried in the tweeter high-pass crossover. It had the best inner detail and overall coherency. As far as I am concerned, there were no negative qualities in its sound at all, which is something I cannot say about any other capacitor brand.

In general, I do agree that simply substituting a high priced boutique capacitor for whatever the designer used in the first place is not always an improvement. That applies to some very expensive caps like V-Caps and Mundorf Silver/ Gold/Oil. But in the case of Duelunds, it's hard for me to imagine a situation where its superior clarity and coherency would not be an overall improvement.

Ssos101,
I`d say there`s no 'guarantee' of results for any change made to an audio component,it depends on the specific situation/application. I replaced the my speaker`s solen cap(tweeter location) with the Duelund CAST and the improvement was quite noticeable.Overall it became more natural,open,transparent with improved tonality and dynamic contrast(these qualities were already very good but became better). I can`t hear a single negative compromise at all.For my application it was a bargain given the level of improvement and refinement,worth every cent I spent.Fortunately the crossover only has a single capacitor,some speakers have multiple caps and the cost can escalate in a hurry.

I also placed Duelund CAST in my DAC(output caps) and again splendid results,no downside with this in any regard. The character or instrinsic sound of the DAC and speaker weren`t change just improved and revealed.
Charles,

They will indeed improve your speaker unless it is one of very low quality. What speaker are you talking about? I use these caps in all my projects and they always sound fantastic!

If your speaker is capable of revealing better gear in front of it etc....this cap upgrade will be a definite improvement. If your speaker is made by Sears as part of their MCS series of the 70's, then perhaps not :-)

Tell us more and we can help.......

Grannyring makes a good observation, the better your system/components the more likely will be the impact provided by the Duelund CAST. They are utterly pure and natural so that much is unveiled sonically(but in no sense are they analytical).Sometimes the capacitor can be the bottleneck.
