Shanling, newly designed "AK4499EQ" 2 top players-AV Watch

MUSIN will release a limited number of Shanling-branded portable audio players from January 14. The price is open-ended, and the store forecast price is about 349800 yen. You can buy it at Fuji Yabic and the direct selling website HeyListen.

This is a player with the new "Shanling Fifth Generation Design". In the more refined circuit design, we choose high-performance acoustic components, SoC memory enhancement and other details, all of which pursue the value as a logo model. The DAC chip "AK4499EQ" manufactured by AKM is installed with dual structure. In order to eliminate the minimal deviation between the chips, the DAC chip uses high-precision instruments to match by hand one by one.

In addition, since the DAC chip has been manufactured, in the case of the end of the initial part, the final sale is carried out directly and there is no reservation for restocking. However, "We plan to release different versions of the'M9'in the future, rather than 'AKM Edition'' with different semiconductors.

Sharp 6-inch display with 2K resolution. A secondary display is arranged in the slot part of the upper part of the display to display the speed, volume, battery surplus, time, etc., of the file to be reproduced. The shell is made of aircraft-grade aluminum and is milled by CNC.

The operating system uses specially customized Android 10. Unique AGLO (Android Global Loss-less Output) technology prevents the sound quality interference peculiar to Android OS. Gain is set to three stages (Low/Mid/High).

The unique low-pass filter technology "CPAF" and operational amplifier + buffer are used to design the circuit and update at the same time. In the refreshed "Ihammer V conversion circuit" and "4ch full balance circuit", the generator and smooth sound are achieved by carefully considering the capacitors and resistors used.

In the capacitors made by ELNA, the circuit components also use high-grade "SILMIC II capacitors", "thin film resistors" with error accuracy of 0.01%, "low loss polymer capacitors" made by Panasonic, and so on.

At the same time, it is equipped with two high-precision crystal oscillators (45.1584 MHz/49.152 MHz) and the "third-generation FPGA technology" with its own adaptive clock sampling algorithm. Reduce the jitter and hand over the clock signal correctly.

Support for PCM up to 768 kHz/32 bits and DSD playback up to 22.4 MHz. SoC uses "Snapdragon665" produced by Qualcomm. For single-ended output, the maximum output value is 460 mW (32 Ω) and the balanced output is 920 mW (32 Ω). The headphone Jack is replaceable, and in addition to 3.5 mm, 2.5 mm balance, 3.5 mm Pro and 4.4 mm balance can also be replaced.

Bluetooth 5.0 compatible, supported codecs only send LHDC/aptX HD/aptX, send and receive LDAC/SBC. It is also equipped with Wi-Fi. Equipped with 8350mAh battery, the continuous playing time of single-ended output is up to 18 hours, and that of balanced output is up to 10 hours. Use a charger that supports Quick Charge3.0 to charge quickly.

The frequency characteristic is 20 Hz~40 kHz. The dynamic range is 122 dB (32 Ω) for single-ended output and 125 dB (32 Ω) for balanced output. The SN ratio is 122 dB (32 Ω) for single-ended output and 125 dB (32 Ω) for balanced output. The output impedance is less than 1 Ω. THD+N is 0.0007%.

Memory 8 GB, storage memory 256 GB. Equipped with microSD card slot, up to support 2TB. The external dimension is 152 × 82 × 22 mm (vertical × horizontal × thick).
