Something in the secret sauce.
After A/Bing everything under the sun the only thing I can come up with is Arch Linux itself.

Try it!
For Debian I've come up with some sound tweaks which many many many people gives an instant and very noticeable improvement...MoOde Audio users seem to like it and post on their forum
