Bakoon Products USC-1001 USB/SPDIF Converter

The USC-1001 is a USB/SPDIF digital signal converter that is inserted between the USB output of a PC and the DAC. Digital audio signals from a PC are typically output from a USB port. This unit has a function to convert the USB digital audio signal output from the PC into the SPDIF signal of the linear PCM.

USC-1001 runs without drivers for use on Windows 10 and iOS. The USB input operates in asynchronous mode, and jitter at the PC output does not affect the SPDIF output. The outputs include coaxial, optical, and balanced outputs of AES/EBU professional digital audio signal transmission standards. Dedicated line transmitters and ultra-high-speed pulse transformers are used for the coaxial and AES/EBU outputs, and high-speed modules in the 30 MHz band are used for the toslink optical output.

Since it outputs a digital signal that rises and falls very quickly, it is possible to obtain a signal with less jitter than the input signal. The output of a CD player has fine vibration linking, which can cause jitter in the rise and fall, but the output of the USC-1001 has almost no linking and a short rise time, resulting in less jitter and improved sound quality.

The USC-1001's coaxial, optical output, and AES/EBU output can be used at the same time. of the company's productsCAP-1006 Digital Signal SelectorBy using , you can further reduce the rise and fall time, so you can expect a further reduction in jitter.

The products of the CAP series have the ability to be used even at the high end.

The PC sound sources I listened to were ripped CDs, 96kHz and 192kHz high-resolution sound sources downloaded from e-onkyo, and pop, JAZZ, and classical.
The audition was conducted in two stages. First, the USC-1001 was played on its own, and then the USC-1001 was played back by connecting the CAP-1006 to the series.
As a result of the audition, whether the USC-1001 alone or the CAP-1006 is connected to it, the rise and fall of the sound rises and falls well, and the outline of the sound is clear. And the music is played vividly in a wide band from low to high frequencies. Therefore, you will not feel bored even if you listen to it for a long time. I felt that this was a common sound that I felt with the CAP-1006 as well.
Until now, PC playback could not produce sound that exceeded CD playback, but with the introduction of the USC-1001 and CAP-1006, we were finally able to improve it to a level where you can enjoy not only CD ripping playback but also 96kHz and 192kHz high-resolution playback. I think it is a recommended product for those who think that PC playback is not good.
