What is the function/pupose of music plyr/streamer


Sorry guys another neophyte here with a simple question.
I am going to set up a Computer sourced link into my audio system (sooner or later, once I figure this out).
I "think" I have the basics of the chain down; Computer, Bridge/Converter, DAC, Amp. However I don't understand what advantage a music player/streamer would afford me.(I will be using a MAC and using mostly Apple Lossless files). So this invites 3 questions for me.
1. Why do I or would I need a Music player or Music Streamer? (they are the same, right?)
2. When used, where should it go in the chain?
3. While these devices often list support for many different kinds of audio files, almost none actually say they support Apple lossless, is this because they don't or they just don't want to spell it out?
Thanks for your patience with some of us new/old (double jeopardy) guys.
But any info would be much appreciated.

The music player/streamer, like say Squeezebox Touch, is a specialized computer designed specifically for streaming audio.

As such it is a special kind of digital audio source component designed to deliver good audio performance that can also be easly both physically and electronically isolated from the computer data source. That's usually a good insurance policy for a good sounding audio system because a general purpose computer is not generally designed to be used as an audio component in an audio system and may often prove to be a source of unwanted noise and distortion best kept isolated from a well performing audio system.

It gets it's data using a normal network data connection (wired or wireless) to your computer and then connects like other audio sources to your audio system. If you use the built in DAC the connection to the audio system is analog. Or You can use the digital output to an external DAC which then connects to the audio system. The DAC used will largely determine the resulting sound.
Is the Squeezebox Touch 24/96 limit confined to the internal DAC (so that a 24/192 DAC could take the Touch signal at 24/192) or is it a limit on the ability to stream?
My understanding is 24/96 is the devices inherent streaming limit, but I could be wrong.

That's pretty good for the <$300 cost these days.
OK Great answers.
Russe- I guess I didn't realize for some reason the player/streamer had a DAC.
Larry- If I'm reading your system right, you dont have a player/streamer, right?
Loomis- I think FLAC and Apple Lossless are not the same. You confirm my suspicion that the player is for managerial duties.
Steve- Is it just Airplay you have an issue with or the whole idea of storing and playing using apple lossless? And
I appreciate the streaming tutorial.
Mapman- You bring up a function for the player aside from its managerial duties. Does not the chain of Bridge/Converter to DAC to AMP isolate the computer in the same respect?

And yes I was afraid I'd hear the old refrain "if it doesn't say so, don't assume it does". I guess I'm hoping the manufacturers were to hung up on space to spell it out
because I know Apple won't recognize any of the acronyms, you know being apple and all.

Thanks this is helping me a lot.
Oh I should tell you guys my system so you know where I'm coming from.
Are you sitting down; I think you should be sitting.

Still works like a champ, but I'm actually thinking of buying some new gear, I just don't want to rush into anything.
