You might be able to scotch (at least some of) the "brightness" by adding weight to the component. Sometimes, roller bearings can "chatter" if the weight upon them is insufficient.
Another possibility is the locations where they contact the component. You could try re-arranging them to see if you hear a change.
While there is much debate within this forum as to whether a support platform should be high mass or low mass, I have been using marble tiles (soon to be replaced by 1" maple platforms).
Whatever road you choose for the support platform, I've found that using an air bladder (i.e. a partially deflated inner tube) adds to the positive effect of using roller bearings. While the roller bearings will provide isolation from horizontal vibrations (the worst kind), adding an air bladder will provide isolation from vertical vibrations. The combination leads to "blacker" backgrounds from which it becomes easier to hear low level information.
So, in sum, I'd say to try using an air bladder on the shelf, a "floating" platform atop the air bladder, your Aurios (or similar roller bearing) atop the platform and finally, the component atop the roller bearings. (When using an air bladder, be sure to deflate it until the "bounce" is as slow as possible. Many who don't like air bladders have auditioned them with too much air in them, resulting in too high a resonant frequency, resulting in boomy, slow bass. When properly DEflated, you'll love what they do.)
