Need advice on how to dip a toe into digital


There are so many A'gon posts about digital, I think I'd like to dip a toe into the media. You can check my System tab to see what I use. In short, my only experience with digital is redbook CD.

So .... I have a new laptop PC and am willing to pick up a DAC or whatever gizmo I need. Is it worth spending any time with SACD? As the question implies, I just want to dip a toe -- not take a plunge. Suggestions would be welcome. Thanks.

I assume you are talking about setting up a computer based music server. What type of music do you listen to and how many CDs do you have? The reason I ask is that depending upon your answers it may not be worth the time and effort unless you're going to be serious about it.
Onh...., yes I was thinking about using my new laptop PC. My music tastes run the full spectrum, from classical to 70s and 80s rock, and jazz. Right now I'm spinning an LP, Delbert McClinton, Plain From The Heart (Capital/EMI ST-12188). I would describe the LP as country/swamp rock of a sorts. Great sound and very musical. I can actually understand the words being sung. I have a couple of hundred of redbook CDs and LPs.

Any recommendations??
The simplest system I can think of is iTunes (free) and an AirPort Express ($99) for streaming and D/A. I use iTunes, on an iMac, and an AirPort Express for streaming and Toslink cable from the AirPort Express into a Pioneer Elite receiver to perform the D/A conversion. The results are very good to my ears.
