Steven Hill, designer and owner of Straight Wire, has released his new Expressivo line of speaker cable ($700/8 ft pair). The cables, which contain four conductors surrounded by multiple spiral shields, include a compressed conductor of special OFHC certified copper and a spiral polyethylene rod that encapsulates the conductor. The net result of his geometry is that the spiral rod only touches the conductor group in a small area, resulting in an effective air-spaced dielectric.

Hill claims that Expressivo’s soundstaging, imagery, and detail retrieval surpass those of his Maestro speaker cable. Expressivo occupies the middle of Straight Wire’s loudspeaker cable line, with three lines above it. The company’s full range of cables ranges in price $1/foot to $150/foot for speaker cable, and from $15 to $900/1m pair of interconnects.
