AudioQuest Audioquest Pearl 1.5 m Micro-USB Cable, USB A Micro-USB B Male/Male USB Cable - Black (1.5 m, USB A, Micro-USB B, 2.0, Male/Male, Black).

In 1982, Sony gave us the 'perfect sound at all times', together with the setting, 'all CD players sound the same, because digital is digital'. This has been refuted and quality differences between CD players accepted as fact. Next came separate transport and DAC combos under the premise 'all digital S/PDIF audio cables sound the same' … until this too was refuted. Now the border has shifted again. Is digital audio really only one and zero? We don't believe that, and once you've had the opportunity to hear the Pearl USB, you won't believe it anymore. Semi-solid conductor made of long crystalline copper (LGC) in concentric arrangement. In a conventional multi-core cable, the distortions caused by the electrical and magnetic interactions of the strands are further amplified as each strand changes its position within the bundle. In an AQ Semi-Solid Concentric cable, strains are considerably reduced because the strands within the bundle maintain their firm relationships with each other. Long-Grain Copper (LGC) allows for a smoother and more transparent sound than cables with normal OFHC (Oxygen-Free High Conductivity) copper. LGC contains fewer oxides in the conductive material, fewer impurities, fewer grain boundaries and thus allows better reproduction. Resin foam insulation. Hard cell foam (HCF) maintains critical conductor geometry. Any solid material adjacent to a conductor becomes part of an incomplete electrical network. Cable insulation and the material of the circuit boards absorb energy. Some of this energy is stored and then released as distortion. Hard cell foam insulation is similar to the PE foam used in the cheaper Bridges & Falls cables and contains nitrogen injections that produce air pockets. Because nitrogen (as well as air) does not
