Queenway USB Processor Filter Purifier Filter High-quality Clock Ultra-low

The USB decoder is the mainstream of digital audio sources. However, the USB signal quality and power supply quality are really bad for HiFi applications. It is the culprit of poor audio quality. The use of technical means to improve the quality of USB signals and the use of high-quality power supplies can greatly improve sound quality. There are a lot of USB linear power supplies and processors (also called filters, filters, purifiers) on the market. I also recommend products that I think are good to users of processors products. However, users report that these products are still not perfect. I also think that There should be  improved deeply. So I began to design my own USB linear power supply and USB processor, so that the user feels blessed after using the two products, the sound quality has an obvious increased .

According to my many years of research, the USB processor should be as close as possible to the decoder. It is better to plug it directly into the USB port of the decoder because the USB line will also degrade the signal quality. The signal after the processor is cleaned should be sent directly to the decoder. Without going through the degradation of the USB cable. This requirement limits the size and weight of the USB processor, greatly increasing the difficulty of the design.

The final designed USB processor uses high-quality clock, ultra-low noise LDO regulator, tantalum capacitor decoupling, PCB high-speed digital wiring technology, compact double-sided mounting design, can bring a comprehensive improvement, higher sound density, digital The digital sound is greatly reduced, the overtones are more abundant, the low frequencies are stronger, and the layers are better.

Plug and play, no need to install drivers.
