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.

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.

The current capacitor on the Vapor Cirrus are the VH Audio OIMP.

These are the standard specs coming with my speakers.

Exclusive Custom RAAL Ribbon Tweeter Element
AudioTechnology 7” woofer with Extended Bass Shelf tuning
Mass loaded constrained layer baffle
Laminated void free baltic birch ply cabinet with mass loaded constrained layer top
Vapor Audio’s proprietary Acoustic Inversion Layer dampening treatment to eliminate cabinet resonance and reduce cabinet wall resonance by over 20db.
Standard Crossover Features:
Jensen 12ga wax/paper Foil Inductors used on woofer and tweeter
VH Audio OIMP capacitors with VH Audio Teflon V-Cap bypass
All point-to-point hand soldered with Cardas Silver Solder
Dueland Resistors
Crossover is contained in separate vibration isolated chamber
Connectivity and Wiring:
WBT 0780 Binding Posts
Wired internally with braided Kimber TCSS for tweeter, Kimber 4TC for woofer

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."

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.

A single Duelund CAST cap (no bypass) will sound significantly better than an OIMP with or without a V-Cap bypass. I am not a fan of numerical descriptions of sonic differences---What does it mean to say something is 10% better? But the benefits of a Duelund over an OIMP will be quite easy to hear and very rewarding. That isn't a very hurdle to surpass.
