In 1982 Sony gave us “Perfect sound forever,”
along with the attitude that, “it’s just digital, so all CD players
sound the same.” That was disproved and qualitative differences between
players became accepted truth. Next came separate transport and DAC
combos, which brought with it the attitude that “all S/PDIF digital
audio cables sound the same…” until that too became disproved. Now the
frontier has moved once again. Is digital audio really just ones and
zeros? We don’t believe so, and once you’ve had a chance to listen to
Pearl USB, you won’t think so either…
SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS:
Solid conductors eliminate strand-interaction distortion. Pearl’s solid
Long-Grain Copper allows a smoother and clearer sound than cables using
regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general
metal industry specification regarding “loss” without any concern for
distortion. LGC has fewer oxides within the conducting material, less
impurities, less grain boundaries, and definitively better performance.
Any solid material adjacent to a conductor is actually part of an
imperfect circuit. Wire insulation and circuit board materials all
absorb energy (loss). Some of this energy is stored and then released as
distortion. Pearl USB uses air-filled Foamed-Polyethylene Insulation
because air absorbs next to no energy and Polyethylene is low-loss and
has a benign distortion profile. Thanks to all the air in Foamed-PE, it
causes much less of the out-of-focus effect common to other materials.
gold-plated plugs are carefully attached with the very best solder.
Through choice of flux and metallurgy, AQ solder has been optimized to
make a low-distortion connection. The difference you hear between
solders is a result of connection quality. AQ solder does not have a
high silver content because the more silver there is in solder, the more
difficult it is to make a good connection.
