| Unprecedented clarity of
treble and high to mid-range, interconnects provide a near match of cable characteristic
impedance with the impedance at the signal source. Offered in RCA and XLR balanced
versions. Virtually distortion free. Featuring a similar geometry and high integrity
construction that has won Alpha-Core's speaker cables extensive praise from reviewers,
consumers, and installers - our interconnects provide demonstrably better
component-to-component analog signal transfer in any high quality audio or audio/video
system.
The design addresses many problems unique to interconnects. In addition to
providing an ideal balance of inductive, resistive, and capacitive characteristics, these
interconnects are also impervious to spurious radio-frequency and electromagnetic signals
that often corrupt audio information.
Unique Flat Design
Alpha-Core interconnects consist of two or three flat, solid conductors sandwiched
on either side of a microscopically thin dielectric. The result, a signal cable with an
extremely low inductance and unprecedented clarity of the treble and high midrange. The
conductors are bands of solid fine silver or high purity OFC copper. They are finished
with transparent jackets of high grade polymer and fitted with Teflon insulated black
chrome RCA or XLR balanced connectors with rhodium or gold plated contacts.
The low inductance, an effect of the Alpha-Core's patented geometry, eliminates
radiated fields while at the same time rejecting extraneous fields. This means that our
interconnect cables can be bundled with other signal and power cables without any risk of
cross talk or line frequency hum. Extensive tests have established that they are
impervious to broadcast bands and other EMI and RF fields, and thus provide a virtually
undisturbed signal path between source components and pre-amplifiers, and between
pre-amplifiers and power amplifiers.
Matched Impedance Reduces Ringing
Another reason for the unprecedented clarity reached with the Alpha-Core interconnects is
the absence of signal reflections and ringing, attained through a near match of cable
impedance with the impedance encountered at the signal source. Because in most cases the
output impedance at the source differs vastly from the input impedance at the load side, a
match at both ends is impossible. But, as demonstrated with the Goertz MI speaker
cables,
a single sided near match is sufficient to effectively prevent mismatch signal reflections
from traveling back and forth through the signal cables and eventually entering the
amplifier feedback loops. |

'Micro Purl',
Copper or
Silver
The revolutionary Micro Purl is cutting-edge transmission line technology. It
contains two 50 microns thick by 2mm wide signal carriers made of solid fine silver or OFC
Copper, placed on each side of a copper ground plane. The ultra thin three layer
sandwich is then twisted (purled) as it is embedded in a heavy sheath of transparent high
grade polymer. The twisting facilitates handling and further enhances EM and RF
rejection. Micro Purl is breaking new ground as professional quality microphone and patch
cables, and as digital interconnects.
TQ
2 'Triode Quartz' Copper or Solid Fine Silver
Since we introduced the new "Micro Purl" interconnect
cables many customers has asked us whether we are planning a new
version of our popular TQ1(discontinued) cable incorporating the same features which
have proven so successful in "Micro Purl". The new TQ 2 is
made in similar fashion as Micro Purl, by twisting the bundle of solid
fine silver conductors and copper ground plane in line with the
extrusion of a tough, crystal clear jacket of high grade polymer. The
result may be coiled and handled like any other cable and will take
considerable punishment without equivalent to AWG 22, and the overall
diameter is .32" versus .25" for Micro Purl. The electrical
parameters and sonic characteristics are the same as those of TQ 1(dicontinued)
except for the fact that the in-line twist has further improved the
EMI and RF noise rejection inherent in the low inductance geometry.
'Tourmaline' Copper
Two thin 18 gauge high purity Oxygen Free Copper (OFC) conductors are sandwiched together,
separated only by micro-thin layers of film insulation. The minute amount of active
dielectric also provides virtually no break-in!
'Sapphire' Silver
Two thin 18 gauge 99.99% pure solid fine silver conductors are sandwiched together in the
unique Goertz configuration. Impervious to extraneous line frequency and RF fields, with
the great ultra clean sound of solid fine silver. |

Alpha-Core
interconnect cables are available in oxygen free copper or solid fine
silver. The electrical
characteristics of Tourmaline and Sapphire interconnects make them ideally suited for longer runs; they can
be made to order in lengths up to 50 feet. |
