I was recently offered a pair of AKG K702 cans, and decided to make sure my audio sources were up to par.
This prompted me to re-encode parts of my audio library using the lossless FLAC encoding, as opposed to WMA/MP3 192kbps earlier.

I thus needed a ripper/encoder, and decided to go for abcde:

$ echo "media-sound/abcde ~amd64" >> /etc/portage/package.accept_keywords
$ echo "media-sound/abcde aac cdparanoia flac id3tag lame musicbrainz replaygain vorbis" >> /etc/portage/package.use
$ emerge -av media-sound/abcde

Then following the advice found here, I went ahead and checked the required read offset for my drive:

$ emerge -av sys-fs/lsscsi
$ lsscsi | grep -F 'cd/dvd'
# look up the read offset for the drive in the list at:
# http://www.accuraterip.com/driveoffsets.htm

I then tweaked the configuration in ~/.abcde.conf:

# ~/.abcde.conf: abcde configuration file

# Actions to take: do the replaygain step (disabled by default)
ACTIONS=cddb,read,encode,replaygain,tag,move,clean

# Default to FLAC encoding
OUTPUTTYPE=flac

# Customize the filename format
OUTPUTFORMAT='${ARTISTFILE}/${ALBUMFILE}/${TRACKNUM} - ${TRACKFILE}'
VAOUTPUTFORMAT='Compilations/${ALBUMFILE}/${TRACKNUM} - ${ARTISTFILE} - ${TRACKFILE}'

# Don't translate spaces to underscores in filenames
mungefilename ()
{
	echo "$@" | sed s,:,\ -,g | tr / _ | tr -d \'\"\?\[:cntrl:\]
}

# Prepend a leading 0 to track # even with < 10 tracks
PADTRACKS=y

# Preserve relative volume differences between the tracks of an album
BATCHNORM=y

# Run on at most 5 cores
MAXPROCS=5

# Set read offset according to http://www.accuraterip.com/driveoffsets.htm
# Use `lsscsi` to identify the drive
CDPARANOIAOPTS="-O 667"

# Put the temporary .wav files on /tmp (SSD-backed)
WAVOUTPUTDIR="${TMPDIR:-/tmp}"

# Open the tray after ripping
EJECTCD=y
# Close the tray before ripping
pre_read ()
{
	eject -t
}

Note that most (all?) configuration options can be found in /etc/abcde/abcde.conf along with a brief description.

And then the magic:

$ abcde

The drive read offset may cause cdparanoia to spew out quite a lot of SCSI errors at the end of the last track, but the output file still seems to be fine.
However, let’s double-check against the AccurateRip database for safety. There is an ARFlac.pl script found at Hydrogen Audio which checks a FLAC-encoded album against the AccurateRip database.
First let’s comment the CDPARANOIAOPTS entry in the abcde configuration, rip a CD and check it using ARFlac.pl:

Ouch. Now with the read offset in CDPARANOIAOPTS:
