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 Bridgeport Magnetics’ 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 Bridgeport Magnetics 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

The 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(discontinued) 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.
