Core decoding is the most high-end AK4495SEQ AK4495EQ is not an ordinary version of the AK4495 is a super version of the series, withSMark, listening sense is better than no S analysis and detail


Now take the United States to upgrade the country half metal sealing double amplifier LME49720HA level, to further enhance the dynamic details. In addition because the upgrade of gold peak IC and the added heat, IC is relatively heavy, start shipping did not pay attention to strengthening, transport 1 bumps off, now shipping has been added fixed, free fall half meters are not guaranteed. Please rest assured to buy


As an upgraded version of PCM1794 and WM8741. 7 days unconditional, Baotui, feel appearance grades, tone not requirements, the signal-to-noise ratio is not high enough, or less than those of 1000 yuan level DAC machine is nice, can return, only pay the return delivery can be (have been sent back to buy courier insurance).


This is the price of the whole machine

Asahi Kasei Microelectronics Corporation (AKM) launched todayAK4495SEQ is a super version of AK4495EQ, higher precision, better sense of hearing, highHigh performance 32 bit stereo DAC, can achieve a dynamic range of 123 dB, stereo and 126 dB for mono output (with optional 7V analog power supply).It is the newest member of audio 4 Pro(TM)Series.The use of a symmetric layout for the left and right channel innovative design techniques can prevent signal quality degradation, as well as a 32 bit digital operation module provides a complete 32-bit processing.

thisAK4495SIntegrated with the newly developed circuit to achieve a rich sound field and bass represents the realization of music playback experience with less distortion. As a consideration of acoustics, the VDD, VREFH, VSS, and VREFL pins are assigned for each L and R channel. In addition, each of these L and R letter props has two tabs to avoid common impedance effects and to achieve a low impedance performance as much as possible..

VRDS-NEO VMK-3.5-20S turntable is the use of AK4495 as the core DAC

USB version of the built-in USB sub card: the use of XMOS in the field of professional audio X-CORE digital signal processing unit, which has a strong processing capacity, is the industry\'s most advanced digital audio solutions. USB Audio 2 asynchronous transmission and playback, and support for very low latency ASIO, KS and other professional audio software interface, support Windows and Mac operating system.


From the appearance point of view, the appearance of this machine absolute seconds out of any one thousand yuan
From the design, more than 1000 of the machine is also used to receive +AK4118 mesnac
From the material, and the mainstream thousands of dollars
From the tone, have confidence in their own, good design and good material, absolutely good sound
From the price, zero profit promotion period


Which XMOS sub card can be used to support the USB port to 192K 24BIT audio format

1SoleSampled the highest end of the AK4118 as a coaxial signal reception, has the lowest in the industryJitterGet through the CPU optimization, mesnac. Cost and performance is much higher than WM8805 DIR0001 CS8416 and other programs

2 using elegant arts aluminum chassis panel, with LCD display, the shape is the most outstanding level of 1000 yuan, and now some of the level of 300USD DAC or aluminum panels with a lot of low-cost process

3 I/V and LPF sample is expensive LME49720NA49860, better than a lot of DAC sampling AD827 NE5532. More natural tone


AK4495 AK is a very good DAC chip at present, the tone is delicate, the sound field is broad, the dynamic is very goodUSB interface to support the need to add USB sub card, P XMOS sub card need to add 180 yuan

Different from the AK4495 scheme, the PCM1794 TAOBAO 800-2000 the level with the road digital receiver IC, such as DIR9001 WM8805 CS8416, the performance is relatively low, it is difficult to give full play to the performance advantages of PCM1794 DAC. The following is a comparison of the performance of each chip

AK4118 has the industry\'s lowest Jitter (clock error), the best compatible compatibility, is the best match PCM1794.

In addition by the relatively high cost of mesnac, on the AK4118 input signal is optimized, with LCD display, so performance and appearance are doing better, I/V also adopts the optimized circuit

Materials and power is also very adequate, the digital part with the most expensive ultra low noise regulator, sound restore more realistic. LPF and I/V conversion part with the PHILPS silver film, the main capacitor is Holland PHILPS, the gold capacitor is the signature of the Nikon HG. Far more than the current level of 300USD DAC good material.

The main sense of hearing, delicate nature, low potential is very good, very good dynamic, details and harmonics have excellent performance



Product core program: AK4118+AK4399SEQ

LPF: the op amp has been upgraded to gold seal LME49720HA

Voltage: ON LM317337 plus super regulator chip LM3941S

Rectifier: 5A VIS ultra high speed

Main filter capacitor: ELNA, Japan Nikon signature version, Germany WIMA ERO and other high-end capacitors

Resistance: GB military brass feet 718 resistance


This is the 220V power rotary switch, turn left turn right



Asahi in December 26th released its new AK4495 32BIT two channel DAC, instead of AK4399.
