The DSDs model adds an AK4497EQ chip to the DSD, and an AK4497EQ for each of the left and right channels. Single-ended amplifier.
Comparison of various models of our store:
Zishan insists:
I2S digital signal quality is better.
Zishan likes to catch up with the new, Zishan DSDs use single chip microcomputer STM32F7+CPLD+ dual audio crystal oscillator to achieve I2S, this is the same idea as auxe m2 and lacquer rainbow c4, but it is higher, reaching 384K 32B. The people who do the technology are honest, please see the picture, the left and right channels are full of 32Bit.
Want a decent DAC.
Zishan likes to catch up with the new, Zishan DSDs directly use two AKM&x27;s sub-flagship AK4497EQ, the unit price is nearly 200 yuan each.
The analog power supply voltage is higher and the ripple is better.
Zishan DSDs analog board op amp part provides up to 9V power supply, and 10 Samsung COG MLCCs form a filter pool.
Zishan DSDs analog board DAC part uses boost + high PSRR LDO regulator + Samsung COG MLCC.
Zishan DSDs analog board coupling uses audio-specific coupling electrolytic capacitor ELNA RE3, rejecting MLCC, tantalum capacitors, aluminum electrolysis, etc. for coupling.
HIFI element 4: The indicator must conform to HIFI.
To test the whole machine index, under the condition of 44.1K, the lucky player index is close to the theoretical value, and the hero is not based on the indicator. The indicator only tells you that the player has no design errors.
Support format
The latest 0.5 firmware supports Apple&x27;s ACC ALAC M4A format, because the form is too lazy to add.
