Query: Wow and flutter is back

I got my DC800 and plugged it into my stero and began sending music from one of my laptops to the DC800 and driving my stereo. To my surprise the blue tooth magic worked and my songs came out of my home theatre system. Then I noticed that the music would speed up and slow down, just like the old days when your turn table (for you post vinyl people, that is how we played records) began to fail. Its called wow and not the good kind of wow. Clearly the clock circuitry inside this box was changing its frequency and causing a poor conversion from digital to analog. I tried this on a second PC just to be sure it did not have anything to do with the digital stream (would would have been shocked if it had) and I got the same result. This product does not perform as it should. You cannot listen to music sent to your stereo from your computer as it has the very annoying wow.
