Dueland CAST PIO


Hello I had a few questions regarding this cap and was wondering if any owners who have heard this cap first hand can help me out.

I am thinking about adding this as a CAP upgrade on the speakers I am trying to get. I have heard from owners on forums saying it made a significant difference to their speakers for the better, but when I contacted some other speaker manufacturers they tell me that just because you add the Dueland CAP does not necessarilly mean you will get better sound. They say withs ome speakers they might sound great, but with some other speakers, they might even make the sound quality lower.

My questions are.

1. Will the Dueland CAST PIO cap upgrade change the signature sound of the speaker as intended by the designer?
Or will it simply make everything sound a bit better not effecting the original sound?

2. How much did the Dueland CAST PIO improve your system?

thanks.

Thanks for all the inputs from the owners of Dueland. I am trying to upgrade the crossover of Vapor Cirrus Black.
I already got the Amorphous RAAL tweeter upgrade, but was wondering if the crossovers were upgraded to the Duelund CAST, if it would make a difference. Ryan over at Vapor Audio suggested that the cap upgrdae to dueland will give it less than 10% of the sound imporvement, but I will be able to tell a difference. The price for the caps are $2,500+.

$350.00 for a single tweeter and $850 or so for the single woofer.

Not sure if both the Woofer and the tweter have to be done together, I will E-mail him tommorow and find out.

I have heard speaker with the Duelund CAST upgrade today, and the violin sounded fantastic.

If somehow I can get the Duelund CAST just for the tweeters that would be sweet, but I would have to check with Vapor audio on that.

Or, do you guys know if they have to be upgraded together?
The current capacitor on the Vapor Cirrus are the VH Audio OIMP.

These are the standard specs coming with my speakers.

Tryingto figure out if the Duelund CAST on the Cirrus will be worth the upgrade. From what I have heard, the parts for these speakers are already pretty great so you wont really hear a major difference.

However, Ryan the designer at vapor did mentin that i WILL be able to hear a difference, just not more than 10%.
This is a quote from the designer at Vapor regarding the Duelund CAST.

"They are the best caps available, period. Also the most expensive caps available, period.

What they do is remove that last bit of hash from the reproduction that you didn't even know was there. The background becomes darker, details are more delineated in space, and everything just sound more present in the room with you."
Thanks for all the inputs. I had a exchange of E-mail with Ryan over and Vapor at he said that the Duelund CAST can be upgraded just on the tweeters. He also suggested since we are gonna go with the single Dueland CAST over the V-OIMP capacitor, that we upgrade the resisters to Dueland CAST as well while we're at it.

Can't wait to hear it!
