Descriptions:

> Martha's Heart - Hidizs Professional HiFi Audio Circuit Architecture
> S9 Pro Plus Martha adopts the fourth-generation professional HiFi audio processing circuit architecture developed by Hidizs Acoustic Laboratory. This is a fully balanced circuit architecture, consisting of four parts: USB interface processor, DAC, independent headphone amplifier and POP sound cancellation system. The DAC uses ESS Technology's flagship DAC chip ES9038Q2M, which uses ESS Technology's patented 32-bit HyperStream® II QUADDAC™ architecture and Time Domain Jitter Eliminator. It ensures the extremely high accuracy of audio data and represents the highest level of audio decoding technology. Its excellent characteristics make it the first choice for audiophiles and high-fidelity music lovers.

> PCM Supports Up to 32bit/768kHz / Native DSD Supports Up to 512
> The ES9038Q2M chip supports a maximum 32bit/768kHz PCM sampling rate, delivering unprecedented precision, capturing subtle musical details, and ensuring a flawless sound reproduction with high SNR of up to 128dB and ultra-low THD+N of -120dB. This revolutionary technology is not limited to high-end audio systems but is also widely adopted in portable devices, establishing itself as part of the future audio standard, offering music enthusiasts an unmatched auditory experience.

By simultaneously pressing both buttons, you can cycle through the six filter effects.

> Here are the waveform graphs and descriptions of these six filter effects:
> (Green Light) Anodizing fast roll-off (Default Filter): Vocals are slightly forward, and high frequencies are extended with reduced resonance.
> (Red Light) Linear phase fast roll-off: Enhanced analytical capabilities, delivering a clean and crisp sound.
> (Blue Light) Linear phase slow roll-off: Enriched harmonics, full low frequencies, and natural reverb.
> (Yellow Light) Minimum phase fast roll-off: Balanced and moderate sound.
> (Purple Light) Minimum phase slow roll-off: Clean sound with a forward position.
> (White Light) Hybrid fast roll-off: Soft and smooth sound with enhanced detail.
