Inspired by the flagship models, Forza and Extreme Mk II
Meticulously crafted and engineered, this limited-edition loudspeaker represents the pinnacle of sonic refinement and aesthetic sophistication. Building upon the renowned legacy of the X Diamond Mk II, this new model pushes the boundaries of audio engineering even further, introducing a host of enhancements and upgrades to deliver an unparalleled listening experience.

Drawing inspiration from the flagship models, the Forza and Extreme Mk II, the X Diamond Signature Edition features top-of-the-line components that contribute to a more transparent sound, with every nuance and detail brought to life with astonishing clarity. Each speaker panel proudly bears the signature of Alfred Vassilkov, symbolising his unwavering commitment to excellence.

Estelon engineering took many years of research and testing to find the right material that would allow the highest quality of cabinet and construction for the loudspeaker’s acoustically engineered complex shape. We developed a proprietary marble-based composite material and special moulding technology to be able to make cabinets with such advanced surface geometry, inside and out.

Reflecting the timeless elegance of the X Diamond Mk II, the X Diamond Signature Edition features stainless steel accent details meticulously crafted by hand, adding a touch of sophistication to its design. Each speaker panel proudly bears the signature of Alfred Vassilkov, symbolising his unwavering commitment to excellence.

The X Diamond Signature Edition sports the latest connector innovation derived from the Extreme Mk II model. Unlike conventional binding posts, the custom-built connectors feature a unique clamp-like design. Spring-loaded for optimal cable attachment, these connectors eliminate unnecessary metal-to-metal transitions, ensuring unparalleled purity and clarity from bass to highs. Crafted from precision 3D printed high-quality polyamide with no metal parts or high dielectric constant materials to compromise sound integrity, Estelon’s proprietary connectors redefine audio connectivity. Adaptable to banana, fork, or bare wire connections, they offer versatility without compromise.

Ther is also an updated filter scheme and topology, incorporating Mundorf Ultra resistors for midrange and high frequencies, and resin-baked coils for bass. These enhancements contribute to a more transparent sound, with every nuance and detail brought to life with astonishing clarity.

To further enhance performance, the X Diamond Signature Edition is equipped with Stillpoints Ultra SS V2 isolation feet. These innovative components ensure consistent sound quality across different floor types while improving soundstage and bass articulation, with every note rendered with precision and realism.

Drawing inspiration from the flagship models, the Forza and Extreme Mk II, the X Diamond Signature Edition features top-of-the-line Kubala Sosna internal cabling with the OptimiZ™ technology architecture. This innovative technology enhances transparency in midrange frequencies and highs, resulting in a larger soundstage, improved separation, and enhanced micro-detail and micro-dynamics. Prepare to be immersed in an extraordinary sonic experience that transcends conventional audio boundaries.
