High-grade Silk
fiber capacitors for Audio
|
|
| |
The SILMIC series are Elna's highest grade audio
capacitors that exhibit superior acoustic characteristics.
An entirely new type of electrolytic separating paper
is used, containing silk fibers. The extreme softness
of silk can mitigate vibrational energy (generated by
the electrodes, by external vibrations and by electromagnetic
fields). Due to it's new electrolytic and foil design
the signal propagation speed has increased (the ESR is
reduced) and a more powerful, yet-mellow, sound is possible
than before. When these capacitors were subjected to aural
evaluations, the high range peak and midrange roughness
were reduced substantially. Also, the low range richness
and power were increased in the obtained high-quality
sound.

Fine ceramic adopted
electrolytic capacitor for Audio
|
|
| |
The CERAFINE series realize high audio quality
by super fine ceramic particles adopted in the fibers
of the electrolytic separating paper. Charge/discharge
speeds are improved, distortions are reduced (less potential
variations due to electro-chemical action of the ceramic),
and electrical noise generated by external vibration is
suppressed. This reproduces excellent sound with real
concert-hall presence, resolution, power, good presence
in the low range and less distortion in the mid and high
ranges.

WHICH AUDIO CAPACITOR?
|
|
| |
Which capacitor to use is difficult to determine without
actually trying. It depends on too many factors. To hear
the potential of a certain part, it's often nessecary
to change other parts too. Experimenting with different
combinations is a more solid way to lift a design to a
higher level. In principle the original music signal has
to be preserved as much as possible, but it's difficult
to tell which parts do. For analysing a music signal (harmonic
structures changing in time), our ears are still the most
useful instrument. But we're all calibrated differently.
To some a SILMIC adds color and warmth and a Black Gate
FK sounds neutral. To others a SILMIC sounds neutral because
it exactly reproduces natural colors and warmth from the
recording, a Black Gate FK sounds more 'hifi' to them,
making the signal more pulsed, peaky (giving attack) and
too clean (filtering out natural timbres).
Often a combination of different (high quality) capacitors
in the right places gives the best result. Best thing
is to try yourself and trust your ears.
Still, we want to mention some general characteristics
as a rough guideline (of course these are our personal,
biased, subjective experiences). These characters apply
for capacitors used either in the signal path or in the
power supply (for digital different rules apply, but there
are simularities as well).
Lower voltage versions of a capacitor can offer more refinement
(it's faster, gives more presence towards the mid-highs).
The SILMIC II is best for reproducing different
timbres, natural colors and warmth in a recording. It
offers most presence in the low-mid range with lots of
texture (tangible). Bass is round and warm, the mid and
highrange are very refined, 'silky', quiet, but with lots
of openess (more open than CERAFINE, less open than Black
Gate FK).
The CERAFINE is also very good for reproducing
different timbres, natural colors, but has a more direct
sound than SILMIC (less direct than Black Gate FK). Bass
is round and warm, the midrange has most presence and
the high range is lively.
The Black Gate FK has the most open and clean sound,
with the main presence in the high range. It sounds thinner,
offers somewhat less texture and timbre. It offers most
pulse, attack in both the low, mid and high ranges.
