Notes: THIS IS VERY WORK IN PROGRESS STUFF, FEEL WELCOME TO EDIT :) (Discuss in Talk:Audiophile Playback#)

Alsa

~/.asoundrc
defaults.pcm.!rate_converter "samplerate_best"	
defaults.pcm.dmix.!rate 96000	
defaults.pcm.dmix.!format S24_LE

An exclamation sign causes a previous definition to be overridden. This syntax can be used with any configuration file assignment.

Dmix is enabled as default for soundcards which do not support hardware mixing.

Pulseaudio

Since Pulseaudio server is not intended to deliver high quality streams for the sake of usability, it is recommended to just not install it.

/etc/pulse/daemon.conf 
resample-method = src-sinc-medium-quality
default-sample-format = s24le
default-sample-rate = 96000

SRC resampling algorithm is very cpu intensive. Setting it to medium quality should work.
