Can you hear any background hiss or channel unbalance (low volume) using iems?
Most laptop only provides 0.5A of current using through the USB. From what I've been told, the amp requires at least 1A current so needs two usb ports to charge.
So there is channel unbalance below listening level huh, damn.
If the hiss is only audible when the dap is playing, it may not be the amp but part of actual recording which is good.
Yes, the HD 650 and the 627X match very well, at least in my book. No problem whatsoever driving the 300 Ohm HD 650.
