I was not sure where to post these questions. So I apologize in advance.

First how many songs would 3gigs allow me to download into my iMac?
What bit rate should I use?
What is the best format to choose downloading your cd's into ones' iMac getting the best quality sound and not using a lot of space? Apple lossless, AAC, AIFF, or WAV?
At present I am using my iPhone for streaming my music via bluetooth thru a Chordette DAC. I intend in the near future to buy Apple TV connected to my existing HT system and iMac and using the iPad for onscreen selection of my cataloged music.
At this time I am using my iphone, Chordette, and the 990 in bypass mode or 2 channel down-mix...I am not complaining about the quality of sound I would like to know if I am connected correctly or if I should have made a better selection?


WAV at 192kbps

Thanks
