Burn In on Aurender N100H


I just acquired an Aurender N100H.  It replaces a Sonos Connect modified by Wyrd4Sound.  After installation, I noticed a very "digital" sound and a lot more noise than I'd been familiar with while listening to the modded Connect.  The modded Connect was connected to my Schiit Audio Gumby via Digital Coax.  Aurender can only connect via USB.
How long do I need to burn this in to get a sense of the quality of the Aurender?  I have a 60-day return policy and if this unit doesn't improve exponentially it is going back.  I would appreciate hearing from anyone with a similar experience and how things worked out.
Also, any advice on the best USB cable for the connection between the Aurender and Gumby?
Thanks

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.


I purchased my N100H slightly used so it was already "burned in". The seller decided to move up to the W20. It came with a high end purist audio cable and sounds just fantastic. I cannot tell if it is the result of the cable but I have no complaints at all with the Aurender.
The N100h is an excellent streamer, been enjoying mine for over a year.  I recenly replaced an AQ coffee USB cable with the Statement cable from http://audiosensibility.com/blog/products-2/digital-cables-occ-copper-and-occ-silver/
Very nice cable, it didn't change the sound signature and just boosted the details and clarity.  Similar to curious, they separate the power and data.  The data is sent through the silver occ conductors and the power is sent through the occ cooper conductors.  If you haven't had a chance to use occ cooper/silver cables, they are a big step up from your normal OFC based cables.  I also changed out the power cable with an occ power cable from audio sensibility and they was a nice change as well.  I agree with the comments that the n100h is sensitive to cable changes but find the right ones and you will be rewarded.
Thanks everyone for the great feedback.  I've been burning in the N100H over the past week and have to say that it is sounding better and better.  I just got the Curious Cable in the mail yesterday and replaced the Supra.  A major improvement with only a few hours on it.  I think this is working out nicely.  I may consider the ISO REGEN and its power supply, but I'll wait a while.  
Hi pg62,

So glad you are warming up to the N100H and like the Curious USB cable.

Don't assume that the ISO Regen will improve your sound. It did not for me. Once you have a clean source like the N100H, it depends on your DAC IMO. Many others really like it in other setups, so YMMV.
