SAEC SUS-020 Stratosphere Hi-End Audio USB Cable (1.2 m)

“STRATOSPHERE” is a designation reserved for the highest-end model in the SAEC cable series. Signals travel quickly and accurately in the vacuum of outer space. With the top-of-the-line STRATOSPHERE cable series, SAEC achieves greater precision and reaches the pinnacle of audio cable performance. SAEC strives to achieve this ultimate in signal transmission.

SAEC SUS-020 Stratosphere is a next-generation USB cable that embodies the ideal audio USB cable for playing high-resolution music data with large capacity and high information content. The cable employs new, unique PC-Triple C/EX conductor, developed for the highest performance and sound quality ever achieved in an audio USB cable.

PC-Triple C/EX, the highest quality audio conductor, boasts an impressive conductivity of 105% IACS thanks to its two-layer conductor structure made of PC-Triple C copper and 5N (99.999%) pure silver by combining two ultra-pure materials into a single monolithic construction. PC-Triple C/EX is an innovative product in which PC-Triple C copper is pressed into a thick 5N (99.999%) silver tube and then compressed by almost 70% using a forging process, which makes the crystalline structure of both the silver and the copper homogeneous and continuous in a single direction.

This new conductor fundamentally differs from all silver-plated conductors in one key respect. It lacks any coloration or sonic signature of silver, traditionally inherent in all silver-plated conductors, as the copper-silver interface is completely homogeneous, and there is no mutual penetration of silver atoms into the copper layer and vice versa. The new PC-Triple C/EX conductor combines the maximum conductivity of silver — forming the geometry of the outer tube — with the maximum efficiency of ultra-pure copper of substantial cross-section, crystallized in the direction of signal flow, to transmit a wide range of frequencies.

This cable delivers stable, high-speed transmission, ultra-low resistance, low noise, a high S/N ratio, and clear, wide-range characteristics.
