Do You Use USB for Streaming?

If so, you might be interested in the cable below

Power supply and USB cable separate audio signal cable

I use an Enercell USB Power Adapter as the power source

ENERCELL AC to USB Power Adapter 5VDC 1000mA 2730414

As it happens, using power from the USB port to supply the DAC's internal USB circuits is common practice.

The dual cable prevents RFI/EMI between signal and power conductors, as in conventional USB cables.

The quality of the cable itself is also very good and performed better than a very good "boutique brand" with both USB-A plugs plugged into my iMac

The biggest improvements I found were in clarity, image and dynamics.

I have compared the sound using the Enercell power supply to using a USB battery pack and could hear no difference, which means the power adapter is very quiet.

Season's Greetings :-)

Power over USB for digital circuits is just like all other digital loads. IT requires a very fast responding regulator. Batteries don't work very well for this, even LI. SMPS power supplies, at least the latest generation can respond very fast, but they also introduce noise due to the switching.

The optimum solution is a very fast linear regulator in a linear supply, like the Power Block. This supply is based on Hynes regulation technology, so it has the best regulator available. Extremely low noise and very fast regulation. No adapter cable needed.

Power supplies are the MOST IMPORTANT part of any audio system, whether for digital or analog sections. The Power Block is the best of these solutions. The others are just toys:
