Dream V14
Truly directional loudspeaker cables
The "Dream V14"
is the newest - and the best up-to-date (2014) revision of the
STEALTH Dream family of loudspeaker cables (excluding only the
separately standing flagship Dream
Royale).
The size (overall
diameter) of the Dream V14 (revision 2014) is larger than such of
the Dream and the Dream V10, the color is white (with four blue spiral stripes that go along the
cables - for the first production run, and gold spiral strips for
the latest production)
The Dream
V14 offers a number of improvements over its predecessors -
the Dream and the Dream V10
This is the first
ever STEALTH loudspeaker cable featuring variable cross-section
along the cable (STEALTH VariCross) - designed to improve
impedance matching between the source (power amp) and the
receiving end (loudspeaker) - which considerably improved
midbass and deep bass performance, without any compromise
whatsoever in the midrange and treble definition and clarity.
The diameter of
the conductive core varies along the length of the cable, while
the outer diameter of the jacketed cable remains the same, and
thus the cross-section of the cables changes along the cable.
This technique - which is absolutely impossible to make using a
machine, and quite difficult to make by hand - is worth the
effort because it dramatically improves the cable resonance
characteristics and behavior via effectively lowering the
"Q" at ALL resonance frequencies - which results in a better
overall tonal balance, lower any coloration of the sound, and
improves perceived clarity.
Because of it's
new geometry (STEALTH VariCross), the Dream V14 cables are
DIRECTIONAl!
The Dream V14
loudspeaker cables are the first in the STEALTH cable line to
feature our new for 2014, completely redesigned solid silver
spade lugs - or our solid silver banana plugs.
We also added a
sliding tuning collar - our best and very effective innovation
for the year of 2014. Moving this collar along the cables allows
fine-tune the sound, and it really works! The initial position
of the collar is approximately 27 to 30 inches from the power
amplifier (the transmitting end of the cable). The optimal
position of the tuning collar is system-dependent. It is
recommended to fine-tune the Dream V14 after it
is broken-in (i.e. approximately two weeks after its
installation in a system) - moving the tuning collar along the
cable for find the best clarity and naturalness of the sound.
Our tests show that on a high-resolution system with high
quality digital units moving the tuning collar along the Dream
V14 creates clearly audible changes in sound, and with
careful tuning the sound quality with the Dream V14 surpasses
the original Dream and the Dream V10 by a considerable margin -
specifically in the deep bass and midbass regions.
The Dream V14
loudspeaker cables have been in testing since early 2013;
several pairs were built in the color code shown below (silverish-white
with blue stripes). No other changes, except for the color -
have been made in the released (production) Dream V14.
Previous versions of the Dream cables:
the
"original" STEALTH Dream loudspeaker cables:
The Dream V10 loudspeaker cables:
While the size
(overall diameter) of the Dream V10 (revision 2010) is the same
as the standard Dream, the color is silver (with four
transparent spiral stripes that go along the cables), and most
importantly, the new version offers a number of
improvements. Inside wire bundles, we added a new core for all
wire bundles. This new core is conductive, carbon fiber-based; the idea of this new core came from our experimentation with pure carbon speaker cables. The pure carbon speaker cable prototypes that we made and auditioned
were very thick: several inches in diameter; the pure carbon
speaker cables sound VERY different, compare to the conventional, metal-based cables: the soundstage is
much deeper and absolutely 3-D. Unfortunately, our carbon prototype is tonally incorrect, and thus we won't be releasing it any time soon. However, in the Dream V10, in same
dimensions as the standard Dream, replacing the non-conductive
core with a carbon fiber based - i.e. conductive - we have been able to get a
better soundstage. To compensate for
the (unwanted) tonal balance shift, we replaced 1/3 of the
original wire assemblies with a flat solid silver AND directly immersed in
Helium, and added a static shield between the wire bundles.
As the result, the tonal balance of the Dream V10 is similar to
the Dream, with noticeably improved - "livelier", tighter bass,
better transient response, and improved immediacy of its sonic
presentation.
The Dream V10 - as the standard
Dream - stereo set consists of
two thick, round cables - which are 35 mm (1.37 inch) in
diameter. The cables split at the ends into positive and negative
runs.
Please take a look at simplified cross-sections
of both the Dream V10 and the standard Dream:
-
The outer layer
of the Dream V10 cable is made of 8 hybrid wire assemblies,
and four solid silver, flat, spiraled, para-vacuum* conductors
and 4 spacers (dividers) - versus 12 identical wire assemblies and 4 spacers
in the standard Dream;
-
Each hybrid wire
assembly is 6.35 mm (1/4 inch) in diameter, made of 8 individually insulated
solid core wires in our proprietary non-resonant distributed LITZ
configuration; two different thicknesses (gauges) of 99.999%
pure solid core copper, and two different gauges of 99.997%
pure solid core silver are used - per each wire
assembly.
-
The wire
assemblies are wrapped around a
hollow, flexible para-vacuum* center multi-core (flexible
Helium-filled tubing).
-
Three wire
assemblies being run side-by-side create wire bundles (triple
runs). Therefore, there are four wire bundles (triple runs) in
each Dream cable.
-
The four wire
bundles (triple runs) are separated by
four blue foam Teflon dividing runs (spacers).
-
The spacers have
the dame diameter as the wire assemblies, i.e. 6.35 mm (1/4 inch).
-
Using dividers dramatically reduces the overall cable capacitance
and thus assures stability (non-oscillation) of any amplifier.
In addition, these four equally
distributed spacers-dividers allows internal STEALTH tuning
collars
XLR versus RCA
Retermination
Bi-wiring
with
Dream cables without any performance loss**
-
The four triple
runs (wire bundles) are being run individually for internal
bi-wire. For single wire, two triple runs being run in
parallel make a positive run, and the other two make a
negative run.
-
Thicker and
sturdier, redesigned STEALTH solid silver spade lugs,
sandblasted with glass spheres for improved contact.
-
Optional - newly
designed solid
silver STEALTH proprietary banana plugs: easy to insert, but
tight (plastic spring-loaded) and virtually unbreakable
(Kevlar composite insert for extra strength).

* STEALTH
para-vacuum tube is a hermetically sealed flexible tube filled
with Helium; fist, Helium is approximately 15 times lighter than
air, and therefore its energy storage properties are extremely
good: about equal to that of a 15-fold vacuum; the dielectric
properties of such environment are even better: Helium is inert
and has no ozone or other ionized molecules, and therefore there
are absolutely no leaks of any kind - and this is better than
any realistic vacuum. In addition, being surrounded by Helium,
the wires will never oxidize or deteriorate. And the last - but
not least, sine - unlike any vacuum - the Helium pressure is
exactly the same as the atmospheric air pressure, there is
nothing to force our Helium to leak, plus the tubes remain
flexible, and the Dream cables are user-friendly - unlike all
other "vacuum" cables (which are very stiff and inevitably lose
vacuum with time - i.e. unlike the Dream, need periodical
service to maintain the performance).
** In other words, internal
bi-wiring with Dream cables offers practically the same performance as true
bi-wiring (but obviously true bi-wiring offer double the
effective (combined) gauge;
Some of the very first - beta testing - Dream speaker cables
were made in white color code, as shown below. Both white (beta)
and blue-black (production) versions
are internally the same.
