I can start with saying I understand what you are talking about.
Yes some speakers depending on design can help... Its all about balance, not just bringing your mid's or tweets down, but also having a good output across the whole spectrum, increased bass speed and resolution can result in a better integration via tipped up digital harsher recordings just as much as trying to turn down the tweets etc...
And also yes Zu's if newer versions with the mundorf Silver oil caps on them (not sure if they are offering that anymore) can in fact help spread out and eliminate some of the "Beaming" associated with cheaper caps and drivers emphasising digital hash and distortion.
Beyond that you do have a good DAC, so not wanting to go out and spend more to take a chance being even further disappointed, Power cable, and interconnects can in fact help smooth out the tone and frequency response with that piece.. It will all depend on the component matching and synergy as to how effective some cables can be.
Good Luck
