That's Hilarious, I took another look at the photo and it does give an optical illusion of tea-candles. Both units have those markings on the caps, must be a factory thing. I shall be hooking the 2nd unit up to some speakers tomorrow to test, and if it works will integrate it on top of the cabinet. Can't wait to see two of them side by side, the displays on them are epic. I need another pair of 12 inch speakers, one step at a time, still poor and will be for a while even though I'm earning minimum wage (cough).
