Below are excerpts from the review:
Another solution where you don’t have to compromise switching to a different DSD format is to switch to a different cable. Tried my new ddHiFi MFi07S and even at high gain, with DSD256, and ear shattering volume with Empyrean, the problem went away once I switched to that cable. I just assume, thicker power wires, less resistance, smaller voltage drop, and just below the threshold of current draw limit which made iPhone happy. Btw, absolutely beautiful cable with high build quality.
