Hi Fred,
I can't endorse Nick's comments enough. Ripping CD's is a loveless task and can take a very long time. If you use dBpoweramp or even EAC to rip to FLAC format, it will mean you only need to "Import" to Sooloos. This will minimise the delay of listening to something on your new equipment.
If you don't do that prior to receiving your new Sooloos equipment it will be very much more difficult to appreciate how amazing it is to "pick and listen" and "swim" around your music collection (You'll soon know what I mean).
I assure you, listening will never be the same.

Happy ripping.
