Seeing that the previous two rounds of audio quality testing failed to find any significant differences in performance based on capacitor type, Allion decided to investigate additional testing strategies. After some research, we found that some audio magazines mention a ‘whisper’ or ‘breathing’ sound, which inspired this third round of testing.
The PC industry is becoming saturated, so many motherboard companies are looking for new markets and high-quality audio market has become their new target. In the high-quality audio device market, new products gradually spread to consumers and related components and accessories appear.
In our first round of audio quality testing (see previous article), Allion used precision test instruments to measure the sound quality of a high-quality PC motherboard. The primary goal was to compare the audio performance with different capacitor types. We used standard audio test criteria commonly applied to laptops, limited testing to the audible frequency range (20 Hz-20 KHz), and only tested the most common audio sampling rates (44K and 48k). However, the test results for the first round o
