See below pic, which shows the two micro USB ports on the back of the DAC.
In short, if possible, both ports should be used for best performance; one for data, the other for power. I think it would be a gross injustice to the designer(s) to assume that this DAC relies on USB power. I suspect the problem is down to communication issues and limited user guidance.
Purely out of interest, I first tried the DAC with only the PC connected to IN1/POWER via a cheap USB cable, so both power & data were provided from the PC using just one USB cable. The DAC worked in this configuration but the sound was congested, dull and uninspiring. I was expecting that outcome though, due to my pre-purchase research. Look on audiosciencereview.com and elsewhere for explanations of the recommended power connections. The unit has been designed to benefit from a separate power supply for optimal performance.
So, I just connected an old 2A micro-USB 'phone charger to the AUX POWER socket. The SQ improved significantly. If and when I have more time, I might try a better power supply but for now I am very happy with the performance.
IMO, although this is far from the last word in DAC performance, the sound to pound ratio is truly impressive....
Hi ! thank you very much indeed for your kind and very helpful reply. It is indeed a very interesting unit
Not to be nitpicky but i do not understand why they have decided for a usb port as dc socket. I like the chuncky ones more.
nothing that a little diy cannot cure
Thanks a lot again
Kind regards, gino
