I thought that Timex digital clock looked familiar. It turns out that I bought that same Timex clock few years ago for $7.99 plus tax at Walmart. I didn't even knew that it has such hidden feature. So naturally I tried to improve my sound system by "installing" in my HT room but it didn't help. Maybe I need two clocks for stereo effect, you know how important to have similar sound stage and timbre matching.
