Giờ em tẩu nặng vì DAC rồi, lọ mọ đọc rì viu hỏi han các nơi thì em chốt lại còn mấy em này có vẻ hợp lý, nhờ các bác (bác Linh, bác Sơn, bác Tư....) cho em lời khuyên nên múc em nào nhé:

2. DAC WM8740 4.0 Wolfson up-sampling 24bit/192KHz USB
Specs:
DAC WM8740 4.0 Wolfson up-sampling w/ USB
Introduction
1 .The DAC system is used 4 pcs of WM8740 chips, as it is the voltage-differential output with 120dB SNR and low distortion of THD+N of -104dB.
2.Used in dual differential mode of two WM8740s in parallel to implement a stereo channel, total of 4 signal output in parallel, it can reduce the signal distortion with more natural sounding background, benefit is SNR improved by 3dB.
3.Using the current highest grade digital receiver DIR9001 and up-sampling chip SRC4192 (Burr-Brown) to handle the up-sampling process.
4.Single op-amp OPA134 x 6 pcs be used for the channel separate totally.
5.24 bit/ 192KHz for up-sampling
DAC structure
1. Three different mode of input (automatic selection),
a) USB -- PCM2902 for USB conversion
b) Coaxial -- Coupling transformer for coaxial input and 26C32 for signal restore.
c) Optical input
2. Highest grade Digital receiver : DIR9001with lowest jitter performance
Support 24 bit/ 96KHz input sampling rate
3. Highest grade up-sampling chip : SRC4192 for up-sampling frequency
4. DAC WM8740 x 4 chips for the DA conversion
5. Op-amp OPA134 x 6 chips for LPF and driver output.
6. SMT process for digital section in order to reduce the inductance and benefit for high frequency transmission.
7. DC output protect for the analog stage
8. High grade of components (TCXO, resistors and capacitors) are used.
Size : 300mm x 188mm x 66mm ( L x W x H)
Panel Color : Silver / Black
Power supply : 110VAC / 220VAC
3. Yulong D100: Yulong D100
Specs:
■SNR: >120dB.
■Dynamic Range: 115dB.
■THD+N: <0.0005% at 1KHZ
■Jitter reduction by using ASRC, custom made 1ppm high precision crystal oscillator
■Using TAS1020B USB controller from Ti in adaptive mode. I2S signal then passed to ASRC and then to AD1955 DAC chip. Same THD+N <0.0005% is achieved via USB input, as compared to coaxial, toslink or AES/EBU input.
■110/120V or 220/240 selectable operating voltage.
■Inputs: Optical, Coaxial, USB, AES/EBU Balanced
■Input digital signal format: 32-192 KHz, 16/24 Bit auto detection. USB input supports up to 24Bit 96KHz
■Frequency response: 20-20KHz-0.16dB.
■Power consumption: <20W.
■Headphone output power: 130mW at 300Ohm, and 900mW at 32Ohm (Measured with chassis connect to AC ground)
■Headphone amplifier with selectable sound mode button on the front panel. According to the maker, the default style Mode 1 is “natural and dynamic”, while Mode 2 “will result in a smoother sound, which is suitable for bright headphones, or if you prefer more “dark and smooth” sound”. In practice, however, I found the two to be VERY similar.
■Two headphone outputs with different impedances: LOW and HIGH
■Dimensions: 250*180*50mm.
■Net Weight: 1.5Kg
■Packing Size: 300 * 300 * 100mm
■Include in the packaging: This DAC, user manual, USB cable. Power cable
