Experience the distillation of reference-level cable technology into an accessible price point with the Shunyata Research Theta Speaker Cable, designed by Caelin Gabriel—a figure whose scientific approach to signal transmission has made Shunyata a trusted supplier to world-class recording studios and heart-surgery laboratories where signal integrity is literally a matter of life and death. Launched in 2024 to celebrate Shunyata’s 25th anniversary, the Theta brings technologies previously reserved for the company’s cost-no-object Sigma-X and Omega lines down to one-fifth the price, employing continuous-cast Ohno copper drawn through heated molds that create a singular crystalline structure free of grain boundaries, formed into proprietary VTX hollow-core conductors that minimize skin effect and eddy currents. The 8-gauge cables feature OFE Alloy-101 copper (C10100, the highest purity commercially available at 99.99%), aerospace-grade fluorocarbon dielectric, and silver-plated copper shielding, with every pair undergoing Shunyata’s PMZ extrusion process at one-quarter normal manufacturing speed followed by four days of KPIPv2 molecular conditioning. Handcrafted in Poulsbo, Washington, the cables terminate in custom STIS v3 cold-soldered connectors with interchangeable gold-plated banana or spade options, presenting themselves in an elegant braided Black Flex mesh. Priced at $1,998 for a 2.5-meter pair, the Theta has earned The Absolute Sound’s Product of the Year and 2025 Editors’ Choice Award, with reviewers declaring it “one of, if not the most musical, affordable, and ultimately consequential cables I’ve evaluated to date”—delivering explosive dynamics, impeccable spectral balance, and an expansive soundstage that competitors struggle to match at two or three times the price.
