Founded in Radboud, Netherlands in 1983, Siltech initially built its reputation on experimental silver, copper, platinum, and aluminum conductors. In 1992, Edwin van der Kley Rynveld acquired the company and, leveraging his experience as a senior electronics engineer, abandoned trial-and-error methods in favor of advanced measurement techniques, bridging the gap between objective performance and subjective listening experience.

Under Edwin’s leadership, Silver Technology, or Siltech for short, invested heavily in all aspects of audio cable design, from metallurgy and dielectric materials to shielding and cable construction. This led to its first-generation (G1) pure silver conductor, arguably the first truly high-end audio cable in the Hi-Fi industry, and reportedly the first such pure silver cable. This laid the foundation for Siltech, which now offers a wide range of truly high-end products, including signal cables, speaker cables, and power cords.

Edwin claims his company uses the purest, highest-sounding silver conductors available, adding that Siltech cables actually improve with age because silver (or a silver-gold alloy) increases in conductivity over time. Undoubtedly, this brand has exceptionally high resale value on the secondhand market, and its cables are highly sought after.

Closer Look
This review focuses on Siltech’s Classic Legend series, positioned above the brand’s entry-level Explorer series and leading the way towards cables with sound quality closer to Canadian whisky standards, such as the Ruby Crown, Royal Crown, Royal Triple Crown, and Master Crown. The Classic Legend is a three-in-one series, including 380, 680, and 880 lines, each offering signal cables, speaker cables, USB, BNC, network cables, and power cables. At its heart is Siltech’s latest G9 silver-gold alloy conductor.

As the name suggests, this is Siltech’s ninth-generation silver-gold alloy, a custom formula developed by the company’s metallurgists in 2021. We learned that they spent over twelve years researching and testing to develop a material that offers significant improvements in audibility and measurability compared to the company’s previous generation, the G7 solid silver-gold cable. Incidentally, Siltech’s other option is S10, a highest-purity solid single-crystal pure silver cable used in its flagship Crown model.

The result of the G9 project is an alloy with conductors reportedly twice as large as its predecessor and significantly reduced grain boundary distortion. This special silver-gold alloy reinforces silver with trace amounts of gold to fill the so-called “microcracks” that appear during silver solidification. This technology has been a key component of Siltech cables since 1997 and has been continuously improved, now reaching a purity of 9N. Notably, the Classic Legend series is the first beneficiary of this process.

Matching this unique metallurgical technology is an exclusive, in-house developed three-layer insulation kit using DuPont Teflon and PEEK materials. These materials, combined with the cable’s special structure, are said to significantly reduce the electrical noise absorbed by the Classic Legend. This, in turn, lowers the noise floor, thereby maximizing its dynamic range. According to the manufacturer, it easily surpasses all previous Classic series cables, both in technical measurements and subjective sound quality.

This review covers the Siltech Classic Legend 680 tonearm cable, which connects my VPI Prime turntable (equipped with an Aidas Malachite Silver moving cartridge) to my YBA PH1 phono preamp. A pair of Classic Legend 880i XLR balanced cables then connect my Gryphon Essence preamp and power amp.

Listening Experience
I’ve had my current reference system for several years and still remember the excitement of first listening after its initial setup. Unexpectedly, connecting the two Siltech signal cables to my system reignited that excitement. I sat there, mesmerized by the newfound transparency emanating from my speakers. These cables delivered a striking clarity, lifting my system away from the sounds I’d heard before. Their exceptional neutrality, in turn, meant they could convey a tremendous amount of sonic detail.

Here, the 680i tonearm cable meticulously handled the delicate signal between my moving cartridge and the phono preamp, while the 880i XLR signal cable ensured minimal message loss or tonal coloration between the preamp and power amp. Car enthusiasts will understand the analogy: it’s like a car that’s been driven thousands of miles and then given a full service and decarbonization. Suddenly, the “first day’s excitement” returned, and you were able to enjoy everything around you.

Furthermore, since the Siltech cables added or subtracted almost nothing from the audible characteristics of my chosen equipment, the difference became even more pronounced when I swapped components, such as when I paired a VPI turntable with an MP-500 MM cartridge. In this case, all the characteristics of the cartridge, as David Price described in his review—”tight, powerful, fast, and insightful, with a smooth tone and a touch of sweetness in the high frequencies”—shone through without reservation. Moreover, thanks to the cable’s clarity, its noticeably more relaxed playability was also evident.

Similarly, this light touch was felt when swapping amplifiers and moving the XLR cables between various DACs, headphone amplifiers, and preamps. So, what do these Siltech Classic Legend cables actually deliver? Almost nothing, and that’s the key. They seem to liberate my system from all constraints, resulting in greater insight, detail, dynamics, and drive. Overjoyed with the results, I couldn’t resist pulling unsuspecting guests into my listening room to listen to familiar tracks like “Methods of Dance” by Japan, “Primary” by The Cure, and “C’mon Billy” by PJ Harvey. I felt a surge of pride, as if I bore some responsibility for the system’s sudden sonic improvement.

Of course, this newfound transparency also makes any potential mismatches in the system much clearer. This, in turn, means that it’s best to invest in this level of cable only after you’ve properly configured the basic components of your system. Of course, we’re talking about a high-end system. The quality of this cable simply won’t be apparent in a budget or mid-range system, but for those who have already invested heavily in their Hi-Fi systems and want to hear its true potential, there’s no need to look any further.

Conclusion: Only when your system is properly configured, and only then, should you consider purchasing this high-priced cable. However, this usually happens when your investment in the system has reached a point where these cables represent only a small fraction of the total system cost. At that point, you can be confident that you’ve gotten a worthwhile upgrade. Therefore, if you want to unlock the potential of your favorite recordings in a way that few can, or truly can, do, then I wholeheartedly recommend trying out Siltech’s Classic Legend series cables.
