Just read a long artical on SOS about clocking on how it doesn't really improves the audio quality. In fact it might even be more unstable. According to them the internal clocks this days are pretty good. Unless u have many gears, then u will need external clock

They never even mention anything about how external clock can give this 3D image in your mix position

Audio world is real tough to understand. Every Tom dick n Harry has their own input. And it can get real misleading when brands try to brain wash people into something that's not true!
Any comments on this?
Here is an email that I received from Black Lion with a bode plot of jitter before and after clocking a 003r with their microclock.

"I've attached a few A/B Bode graphs to this email for you to look at. They are in PDF format. These were tests taken using our Audio Precision SYS-2722, which is a state of the art audio analyzer. Both of these tests measure jitter performance at the converter chip itself; one is a stock 003 using its internal clock (int003), the other is a stock 003 clocked externally to our Micro Clock (wck003). Each unit was set to 48khz sample rate, and the jitter measurement was taken between 0 and 100khz. Since jitter typically resides in the low frequency domain (about 0hz on up to approximately 1/2 the clock frequency), you'll notice the amount of jitter in each graph is highest from 0-10k, and then slopes down gradually as it approaches the upper end of the test frequency. What's most interesting to note is that the jitter performance of the 003 clocked externally (wck003) is lower than the internally clocked 003 by roughly an order of magnitude! Not only is that pretty impressive, but it pokes a rather large hole in the prevailing theory."
