You're right. I'm going to use EAC - almost final point. Almost ? Yes,
'cause I promise I will try to hear differences some day, using an USB
key with different WAVs into it (one from EAC, one from other tools like
RipStation Micro, cdparanoïa...), plugged into my Yamaha DSP-Z7.
Thanks everybody
Do a comparison with the wav files.

If two rippers produce two files with the same checksum, the files are
identical. That really is all that needs to be said on this subject...?
EAC and DBPoweramp and CDParanoia all rip accurately if setup correctly
and used with undamaged discs. The rips do not sound any
different...because they

No. I meant : rip with EAC/dbPowerAmp (useless if already done), re-rip
with another software (like RipStation for example). And just hear.
Obviously, if checksums are equals (RipStation doesn't seem to handle
