AudioQuest Q-2 3.0m
Can a speaker cable sound great, be practical and easy to use, be sexy and be easily affordable? Yes! Q2's inner Long-Grain Copper (LGC) conductor is surrounded by an outer spiral of 11 strands of LGC. The result is AQ's new flexible Solid+ Concentric Conductor, with sound quality even closer to that of an ideal solid conductor and yet big enough to make a great cable with only two simple-to-prepare conductors. Then, the two conductors (+ and -) are spiraled for minimum inductance (inductance makes sound seem out of focus), and maximum clarity and dynamics...and then this ideal cable is given a sexy, square, deep black outer jacket.
SOLID+ CONCENTRIC LONG-GRAIN COPPER CONDUCTORS
Solid conductors prevent two very common sources of distortion: imperfect strand-to-strand contacts and magnetic interaction between strands. However, if a conductor as large as in Q2 was a single solid, not only would it be very stiff, but, due to skin effect, it would also have a very unnatural sound—like an aural roller coaster. Q2’s Solid+ Concentric Conductors comprise a perfect circle of 11 smaller strands of LGC copper spiraled around a single larger strand of LGC. The result is a flexible conductor with sound quality approaching that of an ideal solid conductor.
LOW-INDUCTANCE TWISTED-PAIR GEOMETRY
A normal speaker cable with parallel conductors has fairly high inductance, smearing energy across time and making the sound dull and unfocused. Two conductors spiraled around one another, provide lower inductance, greater clarity, and superior bass-to-treble frequency extension.
