ER-20 Benchmark Power Cord

BENCHMARK™ Power Cord
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.

Setting a New Standard
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.

Pairs Nicely With Power8™
The Power8™AC Power Box is one of RSX’s  best selling products. It seems that nobody ever has enough high-quality power outlets, and Power8 is a great way to add more. It needs a power cord to connect it to the wall, though, and BENCHMARK ER-20 is an easy and affordable way to get some of the kind of award-winning sound that Bob Levi described as “…indistinguishable from my $3,500 and $7,000 power conditioners..” in his 1/29/2020 Positive Feedback Power8 review.

RSX Technologies’ I.C.E. (Intensified Cryogenic Enhancement) process is a multi stage cryogenic treatment engineered specifically for high performance audio conductors. Unlike standard cryo—which uses a single freeze/hold/thaw cycle—I.C.E. employs multiple freeze cycles, lower temperatures, precise hold periods, and controlled partial thaws to more completely and permanently optimize copper’s molecular structure.

The I.C.E. process uses:

• Lower minimum temperatures than standard cryo
• Multiple freeze cycles, each deeper and more precisely timed
• Stabilizing hold periods that allow molecular structures to settle
• Partial thaw intervals that relieve internal stresses
• A final deep freeze pass that permanently “locks in” the optimized lattice

The result is cleaner grain boundaries, reduced micro distortion, and smoother electron flow. I.C.E. treated RSX cables deliver greater clarity, more detail, faster transients, and a deeper, wider soundstage. Spatial cues become more precise, dynamics more natural, and the overall presentation more lifelike.

I.C.E. is not just another name for cryo—this is a purpose built enhancement which elevates RSX’s premium copper conductors and advanced design to an even higher level of sonic performance.
