AEDIO Japan has considered the most important key factor to build good sound system with digital audip equipments is,
Lower noise of digital data transfer on SPDIF, AES/EBU or other data transmission of digital audio data.
Especially music signal related noise (jitter --- in time domain noise is converted as jitter)
To achieve this ,
upgrade power supplies to digital ICs to reduce noise from power supplies
shield digital ICs each other to reduce digital ICs' radiation noise which is very dependent on music source itself
remove range limitation devices such as digital line isolation transformer ,these produce imaging noise of digital music data
use XLR(AES/EBU) connection or very good balanced connection to get good Common Mode Noise rejection
use low noise stable clock signal rather than absolute world clock precision ones.
consider about noise (phase or jitter) rather than simple precision specification
Thus our deliverable is SIMPLE, balanced , external clock based transport and D/A conveter was created and driven by low noise multi-power supplies stable clock MCG-01
