Topping E50 MQA Full DAC ES9068AS XU216 32Bit/768kHz DSD512 PCM768kHz Decoder RCA TRS Ultra Low Noise Preamp (Silver)
ES9068AS DAC Chip--- E50 uses the latest high-performance DAC chip ES9068AS. Our excellence in design and engineering provides realistic and transparent sound quality.
The sound quality is good enough for all kinds of applications--- With the help of careful design and adjustment, E50 provides a distortion as low as 0.00009% and a dynamic range of 126dB, providing you with perfect sound quality. This also makes E50 suitable for applications: high-fidelity PC-HIFI system, mobile phone/tablet OTG, CD player/turntable external DAC, digital broadcasting external DAC, TV DAC, and so on.
Ultra-low jitter for USB inputs, jitter is no longer anxious--- Using CPLD to process the clock and greatly optimize the digital signal, achieved incredible jitter suppression capabilities. The use of new technology makes the femtosecond crystal and external clock no longer needed to suppress jitter.
5V power supply, anytime and anywhere--- E50 uses a DC5V power supply, which can be easily accessed almost everywhere. You can power it up by USB port of PC, mobile phone charger or even a power bank. Note: The product does not provide a 5V power adapter.
All inputs support Auto On/Off function--- E50 auto On/Off function, it will automatically turn on and set to the input which the signal is valid. And when the signal of E50's selection is not valid for 1 minute, E50 will turn off automatically.

Some upgrades - On the E50, the traditional optical and coaxial input not only supports 24bit192kHz PCM, but also supports Dop DSD64 and MQA rendering.And using CPLD to process the clock and greatly optimize the digital signal, achieved incredible jitter suppression capa- bilities. The use of new technology makes the femtosec- ond crystal and external clock no longer needed to sup- press jitter.And you can choose "TRS only", RCA only" or TRS+RCA" output to meet different usages in the systems
5V Power Supply - TOPPING E50 uses a DC5V power supply, which can be easily accessed almost everywhere. You can power it up by USB port of PC, mobile phone charger or even a power bank.(Note: The product does not provide a 5V power adapter.)
Preamplifier function - E50 has preamplifier function So you can control the output volume on the remote control. This will provide great convenience when connected to a power amplifier or monitor speakers. And also help you leave the budget for a preamplifier

Nobsound G2 Subwoofer Power Amplifier Mini Mono SUB Amp 100W PBTL BTL Bridge Home Theater
G2 can be used as a sub amp or a mono channel amp. It has a mode switcher which can change between SUB and PBLT modes conveniently. Equipped with 19V 4.74A high quality power supply.
Applications: ① G2 can be used as a subwoofer power amplifier for passive subwoofers; ② G2 can be used as a mono amp to drive single channel. You can use two G2 to drive left and right channel separately, which are known as PBLT / BTL Bridge amp. Compared with normal 2.0CH amps, it can ensure totally no interference between two channels and can provide higher power.
It has a gain setting which allows 4-level of output level setting (20/26/32/36 dB). It can keep the purity of the sound and avoid the resistor influence. Besides, it also has a bass cutoff frequency control knob.
It adopts TI TPA3116 and NE5532 op-amp, which can offer 100W high power and can drive most home sub and mono speakers. Its optimized circuit can ensure totally no background noise. Besides, it also built-in speaker protection circuit and low pass bass filter.
