AC power cords are much more complex than they seem: Even the simplest power cord — just a pair of insulated wires with plugs on them — still operates on the same physical principles and is subject to all of the same operating concerns as any other cable in your system.
That means that it has resistance, capacitance, and inductance; is subject to capacitive discharge effects; and, unless it’s shielded (NOT just grounded) it can be affected by RFI and EMI noise, both field- and line-coupled, to audibly degrade the sound of your system. To provide clean power every component in your system needs to sound its best, your power cables need to be designed and built with fully as much concern for materials and technology as goes into your phono cables, interconnects, and speaker cables. That’s what RSX does, and you can easily hear the difference.
All RSX AC Power Cords Feature:
BENCHMARK ER-20 is something new to RSX. Hand terminated, like all other RSX cables, it’s the first RSX cable ever specifically designed to have its all-important conductor assembly machine made instead of hand-crafted from multiple components. This saves hours of hand labor and allows RSX to devote more of its production budget to better sound.
BENCHMARK AC Power Cords are now available in standard 6 ft. lengths and in 3 ft. lengths to avoid system clutter and the inductive losses that coiling excess cable length can produce.
BENCHMARK truly is a benchmark product. Laboratory-grade™ copper, low dielectric constant, high dump-rate primary insulation, Balanced-Field™ geometry, 100% coverage shielding, special outer jacketing, and highest quality gold-over-pure-copper connectors are all used in BENCHMARK ER-20 Power Cords to give clearly audible performance far beyond its modest price point. BENCHMARK ER-20 IS THE new standard for affordably priced AC Power Cords.
RSX PRIME™ AC Power Cords are made of multiple individual connectors of ultra-pure Laboratory Grade™ copper. These are directly insulated with a premium Teflon™-variant fluoropolymer, bound together into RSX’s exclusive Demand Coupled™ design with Kevlar® fibers, and then ‘Faraday Cage’ shielded with a bi-metallic braid over LDPE polyethylene.
RSX’s high-quality geometry, shielding, and insulation help improve your system’s sound by reducing noise and capacitance/inductance-related problems. RSX PRIME’s 12+ AWG (per conductor ‘leg’) construction also reduces resistive losses by using 3.3 times as much copper as an ordinary 18AWG ‘heavy-duty’ power cord; even so, they remain highly flexible. All of these things make your system sound better and make RSX PRIME™ the AC power cord you ought to buy.
RSX’s MAX™ AC Power Cords are the next step up from RSX PRIME™. With multiple ultra-pure Laboratory Grade™ individual conductors totaling 10+ AWG per conductor ‘leg’, RSX MAX has nearly five times the metal of an ordinary “heavy duty” power cord to lower resistance and deliver more and cleaner power faster while still remaining supple and flexible.
To address other issues, including capacitance, inductance, and capacitive discharge effects, Teflon™-variant insulating materials (dielectrics) are used at every internal point of the cables’ exclusive Demand Coupled™ design, including under its full Faraday Cage bi-metallic shielding.
The effect of all this is better, faster, cleaner power delivery, and a clear and noticeable improvement to the sound of your system. Buy RSX MAX™ AC Power Cords to hear how good your better-quality system really is.
RSX BEYOND AC Power Cords are also Roger Skoff’s very best ever. Given the limits of theory and present-day materials technology, they, too, may well be the very best cables of their kind possible and without significantly improved materials or increases in our knowledge of how things work, they may remain the standard by which all AC Power Cords are judged for years to come.
Combining all of the features of RSX PRIME™ and RSX MAX™, RSX BEYOND™ AC Power Cords add even more ultra-pure Laboratory Grade™ copper, to enlarge their conductors to a 9+ AWG ‘spec’, while still keeping full flexibility. This plus specially-designed connectors for BEYOND™ only lowers overall resistance to the point of insignificance, while adjustment of RSX BEYOND’s™ exclusive Demand Coupled™ design and the use of Teflon™-variant fluoropolymers for even its outer jacketing work to further minimize capacitance and inductance – related issues and make RSX BEYOND™ ‘The New Best in the World’.
