Operation and Features
Make sure the supplied voltage is the one required by the device. Please ensure the
quality of the connecting cables, paying particular attention the coaxial digital cable. Often,
numerous tests have revealed the importance of this cable for obtaining the best sound
quality. The transport unit which is responsible for the extraction of numeric data, is
affected by jitter, which is non-temporal coherence. In more recent years, this issue has
been taken seriously by some manufacturers, significantly improving the results in terms of
sound quality. Aqua - Acoustic Quality counsels that this quality should be carefully
assessed in order to achieve the desired result.
