I have 1500 cds

Ok, I recently received an ipod for my birthday and after reading this thread, set my itunes cd import to AIFF with custom settings to match the cd sample rate. Will this give me the best itunes has to offer?
I do plan on moving files to external hard drive at some point.

Look into the Music Vault II product sold by Sound Design. It is a network memory device that has two hard drives for saving mirror images of your music fles. There are three versions of the MV II one that holds 1600, 2400 and 3200 CDs. The MV II has a disc drive for ripping your CDs to the drives. Neal at Sound Design has been very helpful with the questions I have asked him and I am likely to purchase the Music Vault 24/192 once I have saved enough cash to purchase it. Check it out on the Internet. It may be just what you need. I am in no way affiliated with Sound Design btw.

I would look beyond itunes to do your ripping. 1500 discs will take some time and a fair amount of prep up front will pay off. Look at dbpoweramp.com. They're an independent software house, nothing to do with me btw, and you may find their website is a very useful resource. They also provide ripping software which ensures you get the best possible rips, and there are batch facilities so that, once ripped, you can convert your collection between different formats in bulk. It's not for the entirely faint hearted, the high quality ripping business, but nor is it rocket science.

I would rip to flac as it's the most convenient full quality format. This also gives you the option of using your ripped files as a source at home, instead of cds. Once you've ripped them, they're so much more convenient to use, and there are sound quality gains to be had as well. Hi fi players are emerging to play the files directly (e.g. Linn DS range).

Sorry to overcomplicate!
