Question for this group. When we talk about USB noise, what does that typically sound like? I recently started having an issue with my DAC only when using the USB connection. It makes a high pitched, almost ultrasonic whine when I begin streaming music from my Lumin to the DAC. This noise isn't present when I use my AES connection.
USB cables and Galvanic Isolation
I've seen that some Dac manufacturers tout having galvanic isolated usb ports.
Does this mean that the Dac is immune to noise/jitter generated by a computer usb port connected to it?
And will a special noise isolating USB cable be required in this instance?
I've seen a lot of threads touting audiophile usb cables and at present I'm not using one. I am using an Amazon Basics usb cable from my computer to a Peachtree DACitx. I have been thinking of upgrading the Peachtree as it was my first external Dac which I am happy with but curious as to how much of a jump in SQ I will hear with a newer more expensive DAC.
Although, I'm not disappointed in the sound I'm getting from the computer, after reading on-line forums that computers generate a lot of noise and mess with the sound I'm a little leary of usb audio.
