Default Cardas Golden Capacitors

Has anyone used Cardas Golden Capacitors? If so, do you have opinions? Comparison with others, e.g., MIT RTX's, V-Caps, etc.?

No.

Sounds expensive. If spending money makes your system sound better, I suggest sending a large sum to me.

The capacitors are made by RTI. I think their construction includes some teflon dielectric, IIRC. I suspect they sound quite good. Order a few and try.

Hi,

A quote from Cardas' website:

"Cardas Golden Ratio Capacitors feature two Golden Proportioned dielectric layers, separated by a metallic coating, which produces "Retained Energy Scaling". The amount and rate of energy released is split between the two dielectric receptacles in proportion to their constants. This composite dielectric eliminates the resonant signature of monolithic dielectric and provides constrained layer damping. "

Unquote.

Ahem....CLD applied to cap winding.
....And all that time I thought that a good filmcap should be wound as tightly as possible.
One of the best examples I've ever witnessed was a Japanese made Taitsu(?) cap which, when sawn in half, looked just like a solid block of metal.
Another manufacturer of excellent caps is French based Eurofarad who are the only supplier of filmcaps certified for the ESA Aerospace programme as far as I know.
They even made filmcaps with copper screw on leadout wires...
No microphony there...

Cheers,

Er, sounds like they designed in dielectric absorption...which can't happen (a property of the dielectric material), and is a negative attribute anyway. Marketing BS is so easy to spot, it makes me wonder how it ever works.

I think they added a bit of teflon to what otherwise was a polypropylene-only capacitor, achieving a combined dielectric absorption somewhere between teflon and polypropylene. From the vantage point of teflon, yes, they designed DA in. From the vantage point of polypropylene, they designed DA out.

I feel compelled, after witnessing such a tasteless signature.

War cry of the Republicans: I reject your reality,and kill you without mercy or human thought!

Hi,

Golden section applied to cap winding implies that every winding machine has to be programmed to step according to that ratio...
Madre madonna...

PP+PTFE+ Metalized...
Lemme guess, the PTFE goes on the bottom, the PP on top and that top layer receives the metal sputtering....Repeat after me, the PP on top, PTFE on the bottom...Oh well, never mind...

Should make for a pretty sizeable cap with mucho self-inductance unless they wind the cap a la MultiCap, I guess...

I'm still laughing about that monolithic signature part and the applied CLD though....
Some people should read a book or maybe take some college courses on Applied Physics.
Next thing, everyone wrapping their caps in a foil of freshly sliced sorbothane, served with a roll of six years old prosciutto directly imported from Tuscany....
With a price tag to match, ma certo regazzi....

Ciao bambini,
