pc vs mac, eac vs itunes


Multi part question: (1) Thinking of going to a musicserver rather than a wall full of cds. I have not been a mac user and would lean toward a pc based system. However, I have not completely closed off the mac option. Main concern is not degrading or changing the data. I have heard that EAC is the best option to insure this and I am wondering if the mac options will ensure the same integrity. I am not concerned with cost of external drives, my plan is to store on a number of external drives and make backups to a spare set of external drives. Looking for feedback on comparison of EAC with a mac option (or is it possible to use EAC with a mac?). (2) Goal is to be able to access everything from sitting on the couch. Any suggestions - both pc and mac based - would be appreciated.

You can determine the offset via a database of cd/dvd drives (via accuraterip website), or by using a known cd in accordance with EAC/dbpoweramp instructions.

As to why,

Most people who rip for archival purposes use the proper offset, which is one of the main advantages of EAC/dbpoweramp.
How much memory required per CD (or per 1000 CDs if that is easier) to store in WAV or AIFF? How much to store in a lossless compressed format?
FLAC (lossless compressed) is about half the size of wav (lossless uncompressed).
And 1 cd = about 500 megabytes uncompressed (wav), so 1000 is about 250 gig in wav, 125 gig in flac. Of course, it depends on the length of the individual cd.

I archive in flac. Or you could use windows media lossless or apple lossless, about the same size as flac.
Sufentanil - I'm not sure why you need RAID. Single disk is fine and Firewire 400 works great. You need to keep backup disk outside of your residence in case of burglary, fire etc - I keep it at work.
