Aurender's "Sound"


Just picked up an Aurender N100H. Great unit. However it's a bit on the warm and dark side, which doesn't sit well with my Pass class A amp. It's like a double whammy of warmth. Great for vocals, but hard to rock out on. But I like the unit and am trying to keep it.

Would love it if I could find a simple way to address this, like with a different USB cable to lighten things up a bit. 

If it comes to it, I might give up the Pass for something more neutral, as nice as this amp is it's not the best for music on the more lively side, or rock. (My tastes and opinions.) Even considering a class D amp like Nord, which is pretty much dead neutral which could peel back some of that warmth and darkness.

So is this a digital question, amp question or cable question? Yes to all.

Has anybody else encountered this double whammy of warmth, and what was the fix. Thanks all.

Do your other sources sound neutral? What are you using for your music files? Your own CD rips? Tidal, Qobuz?
I’ve had a ‘double whammy’ of warmth before. Having a Vinnie Rossi L2 DHT preamp and tried a Terminator DAC with it. To warm and no life to the sound. It’s rough having warmth at the source, that’s a hard one to fix down stream, as that warmth (which can also be some missing information) is in the signal and not just from cables or warmth at the amp (that IMO can be dealt with some upstream)... Sorry I don’t have a suggestion. 
Not sure if you have these features, but if you have digital filter options and/or the ability to upsample those may fix what ails you. :)
I have never viewed upsampling as a fix for anything...it can however mask underlying problems with your gear that sound poorly in native.  
Hey  @three_easy_payments

I've been thinking about the whole upsampling thing.

While it does not provide more data, it does change the behavior of the upper octave's filter, sometimes by a couple of dB.  A significant, audible amount.
