Streaming for beginner

I think I am less knowledgeable than many beginners on streaming and downloads. Hoping I made a good choice I bought a Bluesound Vault 2i and ripped about 170 CDs, all of my CD collection. With customer service help I made three spare copies of what the Vault had ripped using multiple passes and metadata on each CD to eliminate the vast majority of bit errors and cover art it took from the internet: two on USB drives - my entire library is only 31 MB on 60 GB flash drives, and a copy I could rearrange in my laptop to index my library by composer; something it would require a cerebral cortex the size of a watermelon to do in the Vault's hard drive of two Terra Bytes. If I need more storage for downloads I add I could put it on a 120 GB flash drive but I doubt I will collect that much more in downloads. I listen to my library through a flash drive I plug into the back of my Vault which is connected to a vintage turn-of-the century MSB Platinum with upgrades. The electronics following are vacuum tube electronics I designed and built myself so I could have things I wanted such as polypropylene power supply filter capacitors in the 1000 Volts I use in the final stage of amplification.  
What I get from the answers to the original question in this thread is there are no free high resolution services even though the Vault has a long list of streaming services and because I have no faith in my economic future, I do not want to be tied to paying for a subscription  so I just purchase downloads in higher resolution than CD. If I am wrong and there is a free service as good as high resolution downloads let me know because I an just a beginner at this.
Thank you in advance.

You have very high end gear to play from CD.  It will be difficult but not necessarily impossible to get close.
The devil is in the details.  Very clean power for everything.  Lots of good LPS, lots of choices.  My current favorite for the price is the Farad3.
In my system I started with an EtherRegen and it was good with LPS1.2 for power.  I added a SOtM sNH 10G with clock and Farad3 for power. Then the icing on the cake was adding an EE Switch8 powered by an Uptone JS2.  Sounds crazy but it keeps getting better.  Then I turned the EtherRegen around and added Fiber to the EtherRegen and SOtM and that was like adding Frosting to the icing.
Also big improvement with the 2 dcbl CAT7 cables and a dcbl CAT6 cable from SOtM.
I found removing all the SMPS was helpful.  I changed SMPS for my REL Longbow's from stock to IFI and it destroyed the sound of my system.  The IFI may have cleaner power output but they added a lot of noise to the rest of the system.  I had to move them off the dedicated lines for the rest of my audio gear.
Roon was another plus for its integration with Tidal and Qobuz and using the DSP, but having the Core on a quiet computer is important and a good streamer counts.  I have an Innuos Statement which is very quiet with its crazy power supply.  I can hear a difference between locally stored files and hi-rez on Tidal and Qobuz and it is bigger than the difference between Tidal and Qobuz.  Tidal is a bit more lively and Qobuz is smoother and a bit more relaxing. 
But at the end of the day it all sounds good and it gets nit picky only when comparing the sources.
Listening to Roon Radio  playing Rod Stewart Mandolin Wind 16/44 on Qobuz now and it sounds wonderful.

I have the same PS Audio gear that you have. I have just taken the dive into streaming with the CI Audio DMC-1. It’s amazing and sounds as good as my PSA stuff. I can’t imagine your being disappointed with it in any way. It’s fun and easy to use. When I had questions as I was initially setting it up, Dusty Vawter (CIAudio and DMV-1 creator) was readily available and extremely helpful. I have at least 2000 CDs and a lot of SACDs and I didn’t think I would ever get into streaming. I continue to be amazed at how good it sounds and am glad I went with Dusty’s new creation.

@gcsakakini,

Thank you for sharing your experience with DMC-1. The audio circuit is indeed very interesting with dual differential outputs. It’s certainly not common for a product in this category. If I may ask, how is your DMC-1 connected with rest of your system? Are you using both outputs? How do you like the app interface? 

Sending some love out to AirPlay, which has facilitated my entry into the streaming world. 
Bought a used Marantz AV7701 and saw it is Airplay ready. So I did the Roon 2week trial and haven’t looked back. 
Have been sending CDs into iTunes (on Windows) for years using Apple Lossless Encoding to haul music around in my iPhone. Now iTunes is my Roon repository. Because of fidelity problems with how I had to connect the preamp to WiFi, I bought a used Airport Express device (1264) for $20 on eBay and plugged it into the CD phono input on my preamp. Roon found it without a hitch. Sounds great. 
With my intro to streaming, I now have Amazon Music Unlimited, too. Discovering new music all over. The only downside is that there’s no connection between Roon and Amazon. Hopefully that will change. 
Got the audio bug over 40 years ago. Tho I don’t have the gear budget some of you guys/gals have, I have a passion for great sound (and a wife that puts up with it). Appreciate the discussion forum very much. I have learned a lot. Thanx all!
