Audience AU24 SX MP

Audience Au24 SX powerChord MP

Twenty Years of Expertise — Optimized for Sources, Preamps, and Low-Current Components

The Au24 SX powerChord MP is purpose-built for the components where AC noise does its most insidious work: DACs, streamers, preamplifiers, phono stages, CD players, and any component drawing 200 watts or less at the wall. These are the devices processing your system's most delicate signals — and the devices most directly degraded by the RF hash, common-mode interference, and ground contamination that a stock power cord delivers right to their door.

The MP brings the full Au24 SX platform to this critical application: 99.9999% pure OCC copper, the advanced wire geometry that Roger Sheker and John McDonald spent over a year developing, the highest quality XLPE insulation, selective ground shielding in PTFE Teflon, in-house double cryogenic treatment, and Furutech's flagship FI-50 NCF connectors. The result, as The Absolute Sound's Neil Gader described after a full review, is a state-of-the-art cord with a virtually black palette of calm for the noise floor — rock-solid soundstage stability, fully realized dimensionality, and a coherence that places it firmly among the finest power cords available.

Why the MP — and Why Source Components Matter Most

The choice between HP and MP isn't about which sounds better in isolation — it's about matching the cord's geometry to the component's operating requirements.

The MP (Medium Power) uses a 13 AWG conductor configuration, optimized for components drawing 200 watts or less. In this territory — DACs, streamers, preamplifiers, phono stages, CD and SACD players, power conditioners — the cord's primary job is not raw current delivery but noise rejection and clean AC delivery to circuits processing vanishingly small audio signals.

This is where AC quality matters most. A preamplifier stage amplifies whatever appears at its input — including noise from the power supply, which is directly influenced by the cord feeding it. A DAC's analog output stage is similarly sensitive. The quieter and cleaner the AC environment these components operate in, the more of their actual capability they can express.

The Au24 SX MP's 13 AWG geometry is tailored specifically for this role — delivering the maximum noise rejection, tonal coherence, and dynamic clarity that the Au24 SX platform achieves, in a configuration matched to the current characteristics of low-power components.

What Makes the Au24 SX MP Different

Six-nines OCC copper — 99.9999% pure. The same ultra-pure conductor used throughout the Au24 SX signal cable line. At this level of purity, grain boundary artifacts, resistive losses, and impurity-induced distortions are reduced to near-zero — providing a fundamentally cleaner path for AC delivery than any lesser conductor offers.

Advanced 13 AWG wire geometry. Over a year of development by Roger Sheker and John McDonald resulted in a geometry that minimizes reactive interference between conductors while maintaining the flexibility and ease of use that Audience power cords are known for.

Highest quality XLPE insulation. Cross-linked polyethylene provides a stable dielectric constant across all frequencies, minimal signal absorption, and superior compatibility with OCC copper — maintaining electrical integrity across the full AC cycle.

Selective ground shielding — in PTFE Teflon. Audience has long avoided shielding power cords due to the dynamic compression that full shielding introduces. The SX powerChord's solution is precise: each of the two ground wires is individually shielded and then insulated in PTFE Teflon, rejecting ground-path noise without compromising the dynamic performance of the signal conductors.

Double cryogenic treatment — in-house. Both stages are performed at Audience's facility, providing direct control over the process. The treatment refines the crystalline structure of every conductor in the finished cord, improving conductivity, signal integrity, and long-term stability at the molecular level.

Furutech FI-50 NCF connectors. Furutech's flagship Nano Crystal Fiber AC connectors — the best-sounding Audience has found in extensive comparison, and entirely appropriate for a cord of this caliber.

What to Expect

On a DAC or streamer, the Au24 SX MP's improvements are often more immediately audible than a power cord upgrade on an amplifier — because the signals being affected are so much more delicate. The noise floor drops, and with it comes a clarity that reveals what the component was always capable of. Imaging becomes more stable and three-dimensional. Tonal colors become more natural and saturated. The music has greater ease and flow.

On a preamplifier, the gains are in the same dimensions: a quieter background, more precise imaging, improved harmonic resolution — the sense that the preamp is working less hard to pass the signal cleanly. On a phono stage, where the signal is most vulnerable of all, the improvement can be dramatic.
