BRZHIFI SU3B Headphone Amplifier USB DAC Assembled Bluetooth 5.1 Full Balanced Output ES9038PRO Chip

Description:
In order to meet the needs of music players and current mastering, DSD128-DSD512 audio source is generally popular, a high-end SU3 decoder is specially created. The core technology of this chip's software and hardware is thoroughly understood and mastered, and the luxury is carefully matched. The materials used make the output sound quality of the decoder reach a very pleasant surprise. The treble is tight, the vocals are round and natural, and the low frequency is full, reaching the state of music selflessness.

Supports Bluetooth 5.1 and for LDAC and APTX-HD protocols at the same time.

Dimensions: 220 x 52 x 143mm (WxHxDepth). Weight: 2.1KG.

Application:
It can directly drive 16-600 ohm headphones, active speakers and power amplifiers. Its level, details, and analysis capabilities are all improved compared to computers and sound cards.

ES9038PRO DAC Chip:
ES9038PRO is a DAC chip with the highest indicators in the industry, with a signal-to-noise ratio of 132dB and total harmonic distortion plus noise -122dB. At the same time it is a 32Bit, 8-channel DAC. From the parameter point of view, ES9038PRO outperforms all opponents in the market, and its performance is 30% higher than that of ES9028PRO.

Highlights:
- ES9038PRO's 32BIT patented structure for Hyperstream DAC and time-domain jitter elimination technology are the current industry performance level. With its high performance, it is enough to satisfy demanding audiophiles
- As a connected computer system, the input adopts the digital daughter card asynchronous receiving solution for Amanero, which is recognized as one of the excellent asynchronous USB audio solutions so far. The USB daughter card uses independent linear power supply
- The output audio low-pass IV does not use a general op-amp module, but uses an op-amp + discrete circuit, the music is more intense, the human voice is more delicate and moist, mellow and natural
- Use the soft control method to optimize the settings of the DAC chip, support DSD and PCM playing formats, and support up to 32BIT 384K high bit rate playing
- Special audio transformer for power supply, low interference, multi-channel low-noise linear power supply voltage stabilizer
- Support Bluetooth 5.1. Support for APTX-HD and LDAC protocol
- The chassis is all aluminum alloy structure, laser engraved

Features:
- Using DSD hard decoding scheme, high precision, rich music details, strong sense of hierarchy, low interference
- Internal high-end 8-core DAC chip, DSD512, for LDAC, HD audio, APTX CSR, for headphones
- ES9038PRO: SNR DNR 132dB, THD+N is -122dB
- Support CD, DVD player, TV, computer, mobile phone for Android and iPhone
- Powerful sound effects debugging. 5 years of research and development history, every components are selected
- Special sealed HIFI transformer. Low magnetic leakage, low noise audiophile filter capacitor array for ELNA
- It adopts multi-line power supply LDO voltage stabilization, which is much better than some external switching power supplies used for cheap DAC, leaving the background as quiet as deep ocean and dark background
- Integrated processing and forming process
- OPA1612 (dual channel) bipolar input operational amplifier can achieve very low noise density at 1kHz. (1.1nV/√Hz) and ultra-low distortion (0.000015%). OPA1612 can provide rail-to-rail output with a swing range of 600mV from the power rail under a 2-k load, which helps to maximize the dynamic range. In addition, these devices also have a high output drive capability of ±30mA
- 2pcs OPA1612 + 2pcs LN49710 form a low I/V and LPF circuit
- QCC5125 module is an upgraded version of CS8675. In addition to supporting for CSR8675's LDAC and APTX-HD protocol, it can also be compatible with Bluetooth protocol for aptx adaptive
- Professional headphone amp circuit: TPA6120A2 is a high-fidelity audio power amplifier based on current feedback architecture. This high-bandwidth, extremely low-noise device is an ideal high-performance device. Its 120 decibel dynamic range has exceeded the resolution range of the human ear
- 4-layer military-grade professional immersion gold PCB
- With a remote control
- The USB port adopts direct-engraved high-end digital interface for Amanero, which is better than that for XMOS-208 when connected to a computer, with better level of detail and lossless transmission
- Supported Sample Rates: 44.1Khz, 48Khz, 88.2Khz, 96Khz, 176.4Khz,192Khz, 352.8Khz,384Khz
- Output Format: I2S 32bit or DSD64, DSD128-for Windows DSD256, DSD512 too
- The new Bluetooth version enables more stable connection, further transmission distance and lower power consumption
- Easily connect to various mobile phones and computers, lossless transmission, CD-level pure sound quality
- Thickened pure copper gold-plated plug-in RCA socket, gold-plated long-lasting color
