I can't tell what kind of feet if any the A2s are equipped with stock. I've put my Visonik desktop speakers on Herbie's Thick Grungebuster pads. That damps and isolates them and the sound gets an inexpensive but worthwhile improvement.

There's a limit to how much money you want to put into cables for little things like the A2s. For example the best mini-to-mini interconnect I know is the Zu Pivot but one of those might run you half the A2s' cost by itself. If you plan someday to upgrade the A2s, you might be better off saving the money. If not, well, try a Pivot then.
