I am very sorry about the confusion. PM sent.
Pardon the dumb question, but is the only difference between the 2 versions that one offers iDevice input and the other optical?
If I were to primarily use a HiFi-M8 with a laptop via USB, then it wouldn't really matter which version I went for?
Also, does using the USB input limit the DAC in any way as seen with some dac/amp boxes?
Yes, when referring to the HiFi-M8 and HiFi-M8 LX, the only difference on the input side is swapping idevice for optical. USB DAC implementation is one of our specialties and both versions will provide our signature sound quality with no limitations.
If everything runs smooth then we are hoping to ship before February.
