My experience with the N100H has never given me an overtly "digital" sound. Quite the opposite. I was coming from modded Mac Mini, which was quite good actually, I just wanted a one box solution and an iPad based control point. It was definitely an improvement over the Mac Mini setup and a more natural/organic sound. I won't say "analog" and open that can of worms because it's not a record player and never will be. That said, the USB cable makes quite a difference in my experience. I started with an Audioquest Diamond USB which is VERY good, and am now using the Curious USB cable (which I prefer). It is a very natural sounding USB cable.
I have found the N100H to be sensitive to power cable selection. I have had good results with an Audience Powerchord "e", Nordost Heimdall 2, and Valhalla. Throwing some Nordost Sort Kones under the unit picks it up a notch also. Beyond that you can try things like an Uptone Audio USB Regen, PS Audio Lan Rover, etc. They all make a difference of some kind with the N100H as I have tried them. Whether the difference will be to your liking and/or worth the investment will be your call. I would start with the USB cable and work slowly from there IF you see the need for any improvement at all in your system, but don't give up before the recommended burn is complete and you have at least tried a different USB cable. I think the N100H is outstanding.
