DACs are relatively straightforward in concept, but creating a truly outstanding one takes a lot of effort. We do have some unique design philosophies for our DAC products.In the past, our DAC lineup has included many technical highlights—for example, our proprietary PLL (Phase-Locked Loop) technology. This ensures adaptive compatibility across different input sample rates while maintaining synchronization between the DAC and clock signal.Another key feature is that our DACs are designed with independent clock input interfaces from the outset. They can accept external clock signals and even allow seamless switching between internal and external clock sources without interrupting operation. While external clock input is typically reserved for high-end DACs, we insist on supporting it even in entry-level models. Our emphasis on clock signal handling is a major differentiator from our competitors.So if we were to expand on this topic, we’d certainly mention more than just two technical innovations.

Generally speaking, our after-sales service policy recommends that users contact the dealer from whom they purchased the product. This is the most direct and convenient way to resolve issues—whether it’s for repairs or replacement due to product faults—allowing for the quickest resolution. This same policy applies to our official online stores. In most cases, we don’t recommend customers contact us directly, because it’s difficult to accurately demonstrate and identify issues without in-person evaluation. Direct communication with us may also lead to unnecessary delays or extra logistics costs and taxes. Working through the dealer allows for more efficient repairs or exchanges.That said, if users have questions about product usage, we’re absolutely happy for them to contact us directly for timely answers and technical support.

This is definitely a sensitive question, but we’re not surprised that it comes up. We respect how different brand designers interpret music reproduction, and we fully recognize that mixing and matching different brands is one of the biggest joys for audio enthusiasts. In fact, we often do this ourselves.

Aside from it being fun, it also helps us discover potential compatibility issues with our own products. For example, I think Violectric headphone amps pair quite well with our DACs. But we don’t recommend that people simply copy our choices. To achieve the sound we prefer, we often modify other brands’ gear to best match our products. Through this process, we also gain completely new design inspiration.

Just like others discover their own pairing experiences, we believe there’s no such thing as the “correct” sound—only the sound that aligns with your own preferences.
