Copper
Our loudspeaker cables and interconnects are composed of copper of the best possible quality. We decided to use this material after experimentation with many other materials, as well as with other copper configurations. Copper delivers the most neutral, transparent, and natural musical signal. All cables employ the purest possible copper. This purity does not only refer to oxygen, but to all polluting materials and metals. All conductors are subjected to a spark test using 6000 V impulse tension before we use them to produce our cables.
Teflon
The dielectric of all Jorma Design cables is made of the purest, non-coloured Teflon.
Connectors
The connectors we use are very
carefully selected for the best sound quality. Where solder is used, it
is also carefully selected for the same reason. The connectors for all cables are assembled with gold-plated copper crimps, with no solder employed.
Conductors
The filling in the conductors is a
special ceramic glass fibre, with threads that is ultra thin. Inside the
conductors are hundreds of these fibres, and around the fibres are thin
copper threads wound exactly in parallel. The conductor therefore forms
a very thin tube that varies in thickness depending on which series of
our cables it is. We found that the thinner the tube is, the
better-sounding results it gives. However, by itself, such a thin copper
tube is not sufficiently stable for normal use. The solution is to
twine the fine copper around a pure ceramic fibre filler centre to get
as close as possible to tube form. While it is very difficult to produce
conductors in this way, the finished product is very hard to damage.
Shielding
Jorma Design cables employ
sophisticated shielding to reject radio frequency interference (RFI) and
electromagnetic interference (EMI) and to stabilise the cables against
vibration and microphonics. All Jorma Design cables (except power chords
that has a different type of steel shielding) are heavily shielded,
with a tin-plated copper that works very effectively in combination with
the special geometry of the conductors to ensure that all of the
incoming and outgoing RFI and EMI are removed without any compromise to
the audio signal.
Structure
In addition to the use of the finest
materials in all aspects of their design, the unique structure of Jorma
Design cables contributes to their natural sound.
Size
One question that is frequently asked about
Jorma Design cables is: Why are they so thin? For that price, shouldn’t
they be thick and heavy? The problem with taking diameter as an
indicator of quality is that making Jorma Design cables thicker would
adversely affect the sound. We have found that using the least amount of
the insulation that surrounds the conductors results in the best sound.
If we were to use more than is absolutely necessary to make the
finished product strong, safe, and long lasting, it would degrade the
sound. That is why our cables look as they do.
Quality control
The “secret” of Jorma Design
products is that every cable is a carefully chosen combination of design
and structure and that it uses the best materials in the world. Every
Jorma Design cable has to satisfy strict criteria before leaving our
factory, and every cable is individually tested to ensure that it meets
those standards.
The Sound
Every Jorma Design cable has to sound
musical. Simple as that may seem, it is one of the hardest things to
achieve in cable design. “Musical” means that the owner of our cables is
able to listen and enjoy hour after hour of music in total enjoyment.
With Jorma Design cables in your system, your concentration is only on
the music. You do not need to worry about the pros and cons of the
cables because they sound completely natural. They make it possible for
your audio system to immerse you in a sound field that you have never
experienced before.
