Dueland CAST PIO

Bill if the gap from the Mundorf SGO to the CAST is large I believe you as you've tried many capacitors and have much experience. I assume the SGO is better than my stock Solen capacitor so thought the contrast might be more subtle. The Vapor builder says 10% improvement, I wonder what cap is he comparing the CAST to?
Charles,

That's true bill, it's purely subjective. I'll sum it up this way, I can only see a very positive result in choosing the Duelud CAST. Good luck Ssos101.

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,

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.

Ssos101,
My crossover only has one capacitor which is at the tweeter and as I wrote
earlier the change was significant. I would speculate that if you only
replaced the tweeter cap in yours you should still appreciate the
improvement.

Salectric asks a good question, if the current capacitor is very average the
CAST will make a greater upgrade impact than if you already have a high
quality capacitor there now. For me the jump from Solen to CAST is a large
one.Mundorf Silver/Gold oil to CAST a smaller gap change would be
expected. Which location has the greater influence on the sound, tweeter or
the woofer? My gut says likely the tweeter capacitor. What does your
builder say? The CAST are so natural, the music reproduced just becomes
more real and has increased emotion .

You can do a lot worse than the OIMP with a small value V-Cap bypass. I believe that the CAST alone (no need for a bypass cap) will just sound more natural and pure. It'd make a very good speaker even better.

Ssos101,
I believe you made a very wise decision,there should be no second guessing as the results will justify the additional cost.Congratulations with your new Vapor speakers.
