dCBL-U2 is a specially designed USB cable tuned based on PC which installed  tX-USB or tX-USBexp, SATA filter, FAN filter and eABS-100 to maximize the best performance of USB audio devices. Since such this specialized setting is beyond the limits of normal PC audio, the result of dCBL-U2 brings the sonic difference between the general USB cables even though in a very brief moment.

The dCBL-U2 is more open, wider and dynamic sound than its predecessor and it has its own unique beauty and elegance with detailed and delicacy sound. In addition, it also present the mid-high range as well as the deep base range in exact detail without any distortion.

 As for the order options, UPOCC Copper wire which is calm and tidy or UPOCC Silver wire which is more open, wide and delicate relatively are available, and you should choose whether the USB power signal needed or not. The length for he standard cable is 1M, and also you can choose 0.5M, or 1.5M or 2M.

 If you choose dCBL-U2 as an option for not including power signal, this option can block the noise entirely from the USB power signal, so it has an advantage in sound. But this option (not including power signal) can not be used with some USB audio devices which should be powered by USB port, so in this case, you should make an option for including power signal. On the other hand, we recommend to use the cable options for not including power signal with SOtM products since SOtM’s all products don’t get powered by USB port.

 If you connect dCBL-U2 to your USB audio systems you will be able to experience the ultimate PC audio sound beyond the limit of CD.

 No power signal option of dCBL-U2 is good to improve the sound since it fundamentally blocks the noise coming through the USB power signal from PC or other source device. But the no power signal option cable can’t be compatible with some devices which should require power from USB port, in this case, you should choose the option for including power signal of dCBL-U2.

 The SOtM’s all USB audio devices don’t need power from USB port to be operated themselves, so you can choose the no power signal option of dCBL-U2 to connect with SOtM’s all products for better & improved sound
