To those with Digital Libraries - Some Questions...

I have a vast collection of CD's and am still buying them, some new, some used, some old artists, some new.  I gave up on vinyl and my son now has my collection of about 400 albums or so.  I do use streaming but more so listen to my CD collection which is ripped to a Raid 1 NAS (2 - 8 TB drives).  I have the music also on my computer HD but only as a backup.  Not really needed as a Raid 1 is a backup system in itself.

I rip using Apple Music and store as Apple Lossless.  Could convert of FLAC but don't find it necessary.  

I have not purchased any digital files directly, so no experience with that option.

I have a Naim Uniti Star which is an all-in-one CD player/streamer/pre amp/power amp and I use the Naim software on my phone or iPad for playing my NAS library, CD directly or streaming.  I also have Sonos systems in other parts of my house and garage and use the Sonos App which can access streaming or my NAS.

I haven't found any difference between playing CD's directly vs from my NAS.  I'm sure others may have different experiences.

@fire_water  -- not sure what's so confusing. I stream from Qobuz and also use my local collection (65k tracks) which is always available even if the internet is down, though that's a rare event for me.  

The big question for you is how to create your local library.  Generally, one either rips CDs or you download files.  You'll need to rip CDs on your computer and copy to the storage drive, or download them and move them to the storage drive. (And don't forget you'll want backups in case something happens to the primary storage device.)  My understanding is the the Pulsar's Sense app works with an external USB drive, however I don't have an Innos product so can't offer any further details.  

@mlsstl thanks for the info. When I said "confused" I was implying if one method is better than the other in terms of sound quality.  Whether it's a purchase of a digital file or an actual CD I'm still purchasing music.  A digital file is quick vs a CD which you have to wait for. At this point in the game I'm just interested in sound quality but which is my understanding that this also depends on the master itself, correct?

@fire_water -- personally I find no difference between a CD rip, a download, or internet streaming with the one proviso that they are all from the same master. Obviously, a remaster will often sound different from the original release. For example, some of the more famous classic rock albums have been remastered multiple times, each sounding a bit different from the others.  And the remaster can sound worse, especially if it was a victim of the "loudness wars".  

However, other people disagree and will state the CD sounds best, or vice versa. I'd suggest that you do some experimenting and decide for yourself.

No difference between rip and CD on my system. If you hear a difference between those of the same mastering the difference is in your equipment.
