Advice on music source

Hello-
I keep going and forth on the music source. I recently ordered the 700i amp from simaudio which will be matched up with transmission audio speakers. I also ordered the Stream magic 6 from Cambridge Audio for internet streams. I thought that I was done... not yet. I am now thinking to add a source for higher quality music. I am looking for a single source that being vinyl or a media server. With the server, I can create playlist with high quality music downloaded from the internet. I am not certain if the equipment that I am getting would high light the difference between the server and vinyl.
What do I lose by going the route of the music server? Your input for this would be appreciated. Thank you!
