This ad is for an 8 foot long pair of speaker cables and they will be custom
terminated in your choice of Gold Plated over Pure Copper 1/4" spade, 9mm
spade, or banana plugs; and either single or bi-wire termination.


There are 1040 Individual strands of copper wire in this cable, divided into
16 insulated bundles that can be bi-wire or tri-wire terminated.

These high powered cables are engineered for a smooth musical performance.
They are made with ultra-fine hair-like strands of the purest best sounding
copper available and grouped into bundles. This makes these quality cables
extremely flexible and minimizes unwanted interactions in the conductors.
Using ultra-fine wires maximizes the surface area of the copper conductors
and fully takes advantage of the great sonic benefits of skin effect in high
powered speaker cable construction. Grouping these hair-like wires into
bundles also means all the models can be bi-wired and some can even be
tri-wired.

The ultra-pure continuous-cast oxygen-free copper wires give the music
warmth and good detail, because it's a virtually perfect Single-Crystal
Copper conductor. All our cables are sequentially cut from the master
spool and serial numbered to keep them in order. Sequential serial numbered
cables are not only continuous crystal, . . . . they are the same continuous
crystal.

And the larger gauge cables give full power and robust bass response in high
powered solid-state systems and even more so in today's best tube amp
systems. The larger the cable's gauge, the lower its impedance. The lower
the impedance, the more power it transmits to the speakers. We recommend
you maximize your power amps' performance and power output by getting larger
gauge speaker cables. Maximize the power and minimize the current limiting
in your speaker cables.

Which model speaker cable should I buy?

With Granite Audio speaker cables, the larger the gauge, the better it will
sound. There are several good reasons for this. The larger gauge has a
lower impedance which allows the cable to deliver more power, faster, to
your speakers. This is important in today's high quality amps and
recordings that have more live dynamic music passages that demand fast
maximum power for full lifelike music reproduction. If you've ever thought
your music sounded restricted, power limited, or otherwise dynamics
challenged; then you should consider trying higher-gauge/lower-impedance
speaker cables & power cords that are less current-limiting on your
demanding system and will deliver the fast full dynamics of your favorite
music. Don't waste your amp's watts trying to drive speaker cables that are
too small or high impedance.

The larger gauge cables also have more hair-like strands of pure copper
wire. This increases the surface area, which increases the skin effect,
which then benefits the high frequencies and overall tonal balance of the
music. Many other brands of speaker cables use fewer strands because it's
cheaper and easier to build. But, I can also put these Brand X cables on
the test bench and measure the high frequency roll off. I've seen a 6dB
drop above 15KHz , making the music sound very dark and dull, with very
little life left in it.

The larger gauge cables also have more bundles of copper wires. This
increases the separation of the conductors and minimizes the interaction
between the conductors. It also improves the capacitance and inductance
measurements in the cable for better sonics.

Our recommendation? Buy the bigger cable and get the best music
performance that your system can deliver. If you like our Granite Audio
Sound, you'll love our larger gauge cables even more. Bigger does sound
better when you're talking about speaker cables.

"Dear Don, Got the Model 570 Speaker Cables yesterday and hooked them
this
morning. Wow. Much nicer than described. Highs are better defined, mids
unchanged, and bass licks rock solid (esp tom-tom, bass drum, and bass
guitar). Very MUSICAL indeed. No ear fatigue. Bonnie Raitt, Sting, and
Carlos Santana never sounded better. Thanks,"
Bob B. Paducah, KY.

More about Continuous Cast Copper.

The most important factor in cable design is the quality of the conductor.
The introduction of Continuous Cast Copper allows the creation of virtually
perfect conductors. The process forms conductors of nearly perfect
structure, with flawless, mirror-like surfaces, and high flexibility and
great fatigue and corrosion resistance.

The grain (crystal) structure of metals has always been a limiting factor in
cable design. Gases and solid impurities collect at the grain boundaries,
forming non-linear (diode) junctions. These non-linearities cause the
harsh, grainy sound quality of many cables.

A one-meter strand of drawn copper wire, 0.3mm in diameter, consists of from
50 to 40,000 individual crystals (depending on the quality of the copper).
Since no conductor is absolutely pure, each crystal boundary becomes a
diode, adding its own non-linearity (however weak) to the signal.

The Continuous Casting process eliminates this source of distortion by
eliminating the grain boundaries. In Continuous Cast cables, each crystal
is 125 meters long. This means that, even in long cables, there's never
more than one crystal junction per strand.

The single-crystal structure permits unimpeded signal propagation. The
result is an extremely neutral sound with grain-free, extended highs that
are open, airy, and detailed. This improvement is apparent throughout the
full frequency range, even down to the bottom end, whose weight, space, and
air are fully reproduced.
