Q2: Can the sound quality be impacted by the cable?
A: In the high-range, clear differences can be seen in regard to physical characteristics of the cable. There are significant, measurable differences between an appropriately designed and constructed cable and an ordinary cable with regard to values for speed of propagation, attenuation, etc. But, even though differences may be clear within the high-range, the overall impact on the physical characteristics of the frequency range essential to listening becomes small.
Although the impact of the physical characteristics of the cable on sound quality have not been clarified, we believe there to be many cases in which sound quality is impacted by such physical characteristics pertaining to the high-range, and our approach has been one of attempting to make various improvements to these characteristics.
In the cable market, however, it is not uncommon to see find low-precision products, misleading labeling and promotional hype based on non-scientific explanations. Yet, in the midst of all those products, there are those that stand out in terms of a feeling of superior sound quality. This stands out among the many mysterious and interesting aspects of the audio world.
Changing cables will in some way impact sound quality. Such changes in sound quality are generally perceived to be positive, so we recommend that listeners take time to evaluate them.
