Not really. Basically, they measured the speed of light in a medium, which was (due to the type of light they were studying) faster than the speed of light usually in that medium. Still slower than the speed of light in a vacuum. Which means Einstein's Special Relativity has not been disproven.
Don't trust Audioholics for science news. Or news about iPhones.
I believe a test like this was also done out of Princeton in 2000, If I'm correct Einstein's theory would only be proved wrong if matter was actually moved faster than the speed of light. Maybe they will start working on something usefull, like if an amplifier can really make a sonic difference in a home setup.
