3rd vote for reclocker/regen on usb side. Wyred4 Sound Recovery can be had used for $110 and I think is better than synchro mesh, but it does lack ground plane isolation. The RuR as it’s known also benefits greatly from an improved linear power supply. You might start with an Audioquest Jitterbug for $50 new, with free return at musical fidelity which will fatten up the bass and mellow your treble. They can also be modified to cut the vbus power which is said to improve the sound. I’ve realized big gains by building an elaborate usb chain. The Bluesound is a well regarded but lower cost and modest usb source, and almost every usb source needs to be improved. Which USB cable are you using? Cardas can help with bass there as well (I use a v1 Clear), but I’ve recently heard great things about the iFi Mercury 3.0.
All that said, the AQ Colorado is a light/lean sounding cable to me. Kind of the AQ house sound, at least before the latest power products moved away from it. I think your Gibraltar is more neutral.
