The new model is called S9 PRO PLUS, and Hidizs gave it the nickname Martha. We're happy to see that many enthusiasts are already calling it Martha. The most significant upgrade of the new S9 PRO PLUS comes from the ES9038Q2M flagship DAC chip. Compared with the previous generation S9 PRO, ES9038Q2M not only has higher performance parameters, but also supports direct button switching of filter effects. There are seven filter effects in total: Anodizing fast roll-off, Linear phase fast roll-off, Linear phase slow roll-off, Minimum phase fast roll-off, Minimum phase slow roll-off, Hybrid fast roll-off and Brick wall. Switching and adjusting according to different quality headphones or sound sources can maximize the best effect of music. In addition, S9 PRO PLUS supports BAL 4.4mm+SE 3.5mm dual output ports, which is more suitable for mainstream headphone plugs. Under 32 ohm load conditions, the maximum output power reaches 180mW+180mW (BAL) and 130mW+130mW (SE). The distortion is as low as 0.0008% (BAL) and 0.0019% (SE), which has better performance than the previous generation S9 PRO. S9 PRO PLUS has a new appearance design. The one-piece aviation aluminum alloy shell processed by CNC has the design style of the Hidizs family. The further optimized length-width-height ratio makes the product visual effect and grip better. Based on the black and silver colors of S9 PRO, a new blue model has been added, which is also anodized and has a delicate texture, light and strong, making it the best partner for mobile audio playback devices. ## Features - High Performance Flagship DAC Chipset: The ESS9038Q2M flagship-level decoding chip is utilized, offering a 32-bit HyperStream QUADDAC QUADDAC architecture and a time-domain jitter eliminator technology to ensure the utmost accuracy of audio data.
