The Apollon cables from Signal Projects are true high-end products. The conductors are a twisted pair, 1.02mm hybrid design of 6N copper, gold and silver combining solid core and multi core, and insulation is triple-layer PTFE, air and polyolefin. Shielding is 1mm aluminium foil together with a high-purity copper braid. The single-ended RCA interconnects feature effectively the same internal construction as the balanced model, using individual signal cores and directional screening. The range includes balanced and single-ended interconnects, tone arm cable (available in two variants to suite different cartridges and with options of XLR, RCA or DIN connectors), digital interconnects available in BNC or RCA 75ohm and AES/EBU 110ohm, power cables with UK or continental connectors and speaker cables. .
Signal Projects firmly believe that although a wire is just a simple connection between two devices, for those whose intention is to realize the ultimate performance of a system it would be totally unwise to rely on simplistic cable applications. The cable manufacturing process is demanding due to the large number of factors that need to be considered in order to maximise performance without adversely affecting sonic characteristics. Factors such as resistance, capacitance, impedance, inductance, skin effect, power loss, proximity effect and many others can affect cables, as can the effectiveness of shielding, grounding, insulation and overall build quality. The application of proper scientific principles produces excellent, measurable results. Virtually all Signal Projects cables have capacitance values of between 35pF and 85pF per metre and inductance as low as 2uH.
