4) slow roll-off, minimum phase filter: Non-Symetrical filter designed to
minimize pre-ringing. Strong punchy bass with good transient attacks
5) apodizing fast roll-off,linear phase filter: Version of Linear phase fast
roll-off filter optimized to improve pre-ringing.
6) hybrid fast roll-off, minimum phase filter: Combination of Linear-
phase and Minimum-phase. Fast transient attack, strong punchy bass,
crisp highs.
7) brickwall filter: On of the earliest designs, intended for highest

All To DSD
When the All To DSD function is turned on, the PCM signals will be
converted to DSD for output with sound quality further improved.
【Principle】All To DSD is mainly about switching digital signals from
PCM to DSD format. So when making digital-to-analog conversion, it
can use DSD format, enriching music styles with clearer and natural
sound quality. In addition, since the lowest format of the DSD is DSD64,
i.e. 4 times of the 44.1k/16bit (just looking at the data size), the All To
DSD function is upsampling the 44.1k/16bit audio signals. Third-party
apps also support All To DSD.
