Budget Music Streamer


I've been trying to get my head around best sound out of a budget streamer. All my CD collection is now in my portable 2TB hard drive as FLAC files and I also have subscription to Apple Music (large playlist). Currently using Apple TV and Airport Express (airplay limiting to 16 bit/44.1kHz) and Apple TV streaming at 48kHz. I have a revealing system and know I can get better sonics by upgrading my digital source. Unfortunately I have been blessed with a good ear for music.  

There are quite a few options out there, each having it's limitations, specially the ability to play Apple music directly from iTunes using a remote without limiting the sampling rate. Do I consider a Mac Mini or build my Raspberry Pi source? Will I get a spdif connection (preference) out of the two? Is there remote control capability to view playlist (I don't intend to hook up a monitor). Or is there a better solution out there for both listening to FLAC files on hard drive and streaming Apple Music? I plan on selling my OPPO player - no use to me, to fund a better DAC (schiit Yggdrasil or BorderPatrol) - hence the digital source is on a budget. Experts chime in..

Thanks lowrider57. Any recommendations for a good cable without breaking the bank? Both coaxial and TOSLink. I am using cables by Morrow Audio in my system. 

Also - I think I will need a more long term/better/scalable solution to my streaming than Apple TV gen4 or AirPort Extreme. Does the Node allow to stream Apple Music - not AirPlay but direct connect to DAC and play music via remote app? 
I have the Pro-ject Stream Box S2 Ultra that will stream from USB to the USB DAC in my Oppo 205. 
This may or may not fit the type of player you might want, but you should check out the latest iterations of some of the raspberry pi-hat players from Allo. I got the Allo Digione, for the reason that it was reviewed a few times to out perform the Aries Aurelic and bluesound node 2, and can be purchased for under $200 with player software installed that can be managed via phone app.

It can be managed via WiFi, has both rca coax and BNC outputs to send to your already excellent DAC. 

And it REALLY sounds great. 

A decent review about the Digione:

@jwricci - how do you like the sound of Allo DigiOne? Can you connect an external HD to it? Can you play Tidal or Apple Music - if so how? I love the fact that it’s prebuilt for you. Interesting that it’s compared to be better than Aurelic Aries and I am certain Mac Mini. 
@jwricci2 Nice find with the Allo!

I have just bought a Raspberry Pi with a spdif card and will try to assemble it and try it out with my dac. Cheaper but much more work. Next step for me would either be a better dac or a re-clocker.

I don't use AirPlay or or AppleTV and have no idea if those works on it. As long as it handles local files, Spotify and maybe Tidal I am happy.
