Apple lossless as a source

I want to play Apple music as a source from either PC or iPhone (or whatever).

Background:

I am rebuilding my system to get back to music.  I have several good but older components.  I don't want to spend 5000$, lol

What I have:

NAD 2200 Power amp- continuous 100 watts at 8 ohms. Its dynamic headroom is rated at 6 dB, which means that it can deliver—in 20-millisecond bursts, twice per second—400 watts per channel to 8 ohms, 600 watts to 4 ohms, and 800 watts to 2-ohm loads.

Totem Tabu speakers- Basically upgraded Totem Model 1.  Somewhere between a Forest and Forest Signature - very nice speakers that would be in the 5k range today.

I've been out of the audiophile stuff for many years (prior to all the digital stuff).  Basically, I want to figure out how to get from Apple Music to the amp in a cost-effective way with the best quality.  I am fairly technical but just haven't kept up with all the digital audio stuff.
