Capacitor blues..... |

Geetings!
We all know there are lots of branded caps like the Auricap, VCap and many
more.
I got to know that these branded caps boast the technique used to make them
especially
when claimed "hand made".
Now, in the other developing countries where most of the branded stereo,
electronic equipments
and all sorts are build using parts from countries like Taiwan, Hong Kong
and China. These
factories which makes capacitors are normally setup by companies from
current developed
countries such as the US, UK end etc ... These new factories make capacitors
which are
machine made and using much cheaper labour as compared to developed
countires. So here
goes my question:
1. How could a hand made capacitor be better than machine made ones? Human
are people and
as we all know, people makes mistakes. However this is less likely in
machines. People have
feelings and this does effect their quality of work-does it not?
2. Cost of production is so much cheaper because of the econimic factors,
hence much lower
selling price. Could it be that people regard cheap as no good?
3: Will there be a significant difference between foil polypropylene against
metalised polyprolylene in
terms of audio performance especially in signal coupling stages?
4. Has anyone heard of Claritycap? The manufacturer claims that their SA
series is at par or better
than Auricap. Anyone experienced it before?
5. How does one truly compare plastic capacitors for quality besides
listening? Does the tech
spec in the datasheet matter? In most cases they look almost the same.
Cheers!

Hi Mark, |
From my view, it's somewhat difficult to answer your many questions because
it appears that you have already done a good job of it.

Capacitors can be wound quite adequately on machines, though teflon is
rather difficult to manage and takes a bit of skill.
2. Cost of production is so much cheaper because of the econimic
factors,

The audiophile market is a law unto itself
3: Will there be a significant difference between foil polypropylene
against
metalised polyprolylene in terms of audio performance especially in
signal coupling stages?
Both are inferior to teflon, for example. Motor runs, however, are
great in the PSU.
4. Has anyone heard of Claritycap? The manufacturer claims that their

ICW - good caps. I've used them. the high end of polypropylenes.
5. How does one truly compare plastic capacitors for quality besides
listening?
I listen. As a general rule I've found that the higher voltages in
polypropylenes sound better than the lower voltages because the
materials used are thicker and this gives better self damping - in
addition to the sheer size and weight. |

I can imagine that for foil polypropylene caps it's easier to exert
influence on the (metal part of) foil thickness and thereby on ESR.
Equivalent Series Resistance should be as low as possible.
Also, the way the terminals are attached to the conducting foil
is important for a low ESR. I guess in the end it comes down
to compare apparently identical cap's of various brands for ESR.
There's quite some info about ESR testing on the web.

Certainly spec's do matter. Part of the spec and an important
selection criterion is the cap's dielectricum. For a description
of cap's on the market, their dielectric materials, properties
in (audio) applications and how to bench test them see:

Above article is in German wich may present a problem for
(some/most of) you. "Elektor" publishes in several languages,
so it may be available in English somewhere on the web.
