Reference Digital Audio 40:

Sets a new standard in digital coaxial S/PDIF signals with its advanced technology and carefully crafted design. Using silver-plated conductors, effective high-quality shielding, and impedance-matched cables and connectors, the Reference Digital Audio 40 creates noticeable sonic improvements compared to competing products. The innovative use of QED Digiloc2™ RCA connectors reduces the return loss by up to 1.5dB compared to traditional RCA connectors, which ensures optimal signal transfer and improved micro-timing of the audio signal. With triple layers of electromagnetic shielding and a 75 Ohm coaxial design, the Reference Digital Audio 40 guarantees a low jitter signal transfer and exceptional sound quality that meets the expectations of the most demanding listeners.

Specifications:

• Silver-plated 99.999% oxygen-free copper as central conductor.
• Extruded foamed Polyethylene (PE) dielectric - for sonic purity and low return loss.
• Double 99.999% OFC braid plus Al/Mylar wrap for 100% electromagnetic shielding coverage.
• Twin leaf 24c gold plated QED Digiloc2™ RCA connectors with high purity copper contacts, pin and low eddy current design.
• 75 ohm coaxial design with close-matching locking connectors for reduced return loss.
