MUSES is a brand of audio semiconductor devices designed specifically for the pursuit of high sound quality. The MUSES series of products are unique in the world and created based on the following concepts:
In other words, development that relies not only on measured values but also a top priority is given to the final sound quality.
Process tuning is carried out using repeated listening evaluations across a range of audio applications. The transistors were developed exclusively with a high emphasis not only on low noise / THD but by constant checking of the sound quality by listening evaluations.
Circuit and layout structures that take sound quality into account, without being bound by chip size restrictions. This has lead to the chip dimensions being approximately four times the size of the chips in more general products.
In general, high quality speaker cables and other cables using oxygen-free copper are said to produce higher quality sound than conventional copper. The MUSES flagship series uses high-purity oxygen-free copper for the IC lead frame to reduce degradation during signal transfer.
Unconventional assembly technologies are used to make the most of carefully selected materials.
(2-circuit operational amplifier)
2-chip configuration for "L-channel and "R-channel". Improved separation and balance of left and right sound.
(1-circuit operational amplifier)
2-chip configuration of "input stage" and "output stage" reduces mutual interference between the input and output stages
