No, this is no Joke! I really do not know how or why it works, I just enjoy music alot better when the clocks are in the room. I know this sounds real crazy but this product really does work. Its the best tweak I have ever tried, its like getting a speaker upgrade! When I first heard about these clocks over on the audiogon forum I thought they were all nuts!! until I tried them out for myself....I'm a BELIEVER now!
