I'm reviving this thread because sidssp asked an important question about 64 bit kernel operation that was never answered.
When you boot up Snow Leopard, it normally boots into 32 bit kernel mode. You can confirm this by going into "About this Mac" then "More Information." Highlight "Software" in the left column. In the right column, it will say, "64-bit Kernel and Extensions" and probably "No." To boot into 64 bit kernel, just hold down the 6 and the 4 key while it's booting up (Once you see the apple, you're fine.) To confirm that you're in 64-bit, the "no" should have changed to a "Yes."
If you have a resolving system, the improvement will be evident. I find that the sound is more relaxed, natural and open.
