Snow Leopard and audio quality

I just took the trouble of making a clean install of Snow Leopard on my dedicated MacMini systems with iTunes 9.

I am convinced that the new software and the clean install have made an extraordinary improvement in my computer & DAC-based music systems.

Tonality, depth, detail, soundstage, musicality: all seem to have improved in dramatic ways.

Has anyone else had the same experience?
Coverto... SL just made it possible for my DAC, cabling, and setup to fully reveal itself and the music (given the facts and limitations of digital files). I am still amazed and pleased at the improvement.

:) listening,

Which OS version number are you all referring to. I've got 10.5x, I think it's 10.56 or 10.58 but forget. I have not moved to 10.6 yet. Is that the one you call "Snow Leopard"?
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.
So if I do a clean install of Snow Leopard I have to back up everything in the computer. When I download all the stuff back into the computer after installing Snow Leopard, what happens to my OSX 10.5.8? Does it go back in as well and then needs to be deleted or how does that work? I don't see where you can isolate all programs in the Mac. It is either take everything out and then put everything back in or nothing. Is that right?
