Enduring Excellence
Originally reviewed in 2020, the QED Reference XT40i has stood the test of time. While new competitors have emerged, this cable remains one of the best choices for speaker wiring in 2025. If you're considering alternatives, check out our recommendations below, but rest assured that the XT40i remains a top-tier option.
Why Cables Matter
Seasoned hi-fi enthusiasts understand the critical role cables play in an audio setup. High-quality cables, whether speaker wires or interconnects, can unlock unrealized potential in your system—something that free, bundled cables simply cannot achieve.
The QED Reference XT40i exemplifies this principle. It enhances clarity and detail in any setup, from a compact micro-system to a high-end configuration. While it may have some limitations at the ultra-high-end, its impact on entry-level and mid-range systems is undeniable.
Compatibility
QED offers the Reference XT40i in pre-terminated lengths:
- 2m: $199
- 3m: $229
- 5m: $299
Given the typical market rates, these prices offer excellent value, especially considering the performance improvements they bring. Even in high-end reference setups, the XT40i maintains QED’s reputation for delivering a clean and insightful sound.
Build Quality & Technology
QED, a nearly 50-year-old British company, integrates innovative technology into the XT40i:
- Air Gap Dielectric: Increases conductor separation, reducing dissipation and capacitance for improved timing and rhythmic accuracy.
- 99.999% Oxygen-Free Copper: Ensures high signal integrity.
- X-Tube Formation: Conductors are arranged in a tube-like structure around a hollow insulating rod. This equalizes current densities, reduces inductance, and presents a stable load to the amplifier.
Sound Performance
For audiophiles who prioritize clarity and precision, the XT40i is a game-changer. The cable enhances the ability of your system to:
- Define instruments with remarkable accuracy.
- Capture room acoustics and recording nuances.
- Deliver precise timing and rhythmic integrity.
From electronic music’s sharp synthesizer waves to the delicate resonance of a cello, the XT40i paints a vivid sonic picture. Percussion hits with remarkable accuracy, and overall, the system gains a newfound confidence and cohesiveness.
While some listeners might trade a bit of clarity for a more relaxed musical presentation, the XT40i excels at balancing precision with dynamic expression. It ensures that instruments remain well-organized and interact harmoniously within the soundstage.
Verdict
For those looking to elevate their system with speaker cables in this price range, the QED Reference XT40i is a compelling choice. It delivers an outstanding balance of detail, timing, and musicality—qualities that are difficult to rival at this price point.
