I have approximately 30K Redbook CD's ripped as FLAC files using dbpoweramp saved to hard drive. And 5K SACD files saved as either DSF or FLAC also have ISO files which I typically convert to DSF.
All files include high res covert art in the folder and have been checked using Tagscanner to correct any issues with metadata,missing coverart, track numbering. issues.
I have an MF Digital Ripstation with dbpoweramp installed and can rip 70+ CD per hour using 6 CDROM drives simultaneously. If you want to save your sanity and not rip a large collection manually which could take an eternity and never have the consistency when the project is completed that mine would provide contact me to talk about having the collection ripped.
Having a large collection which most people comment that you can never listen to all of that music is mostly correct. The point isn't that you will listen to all of the music it is akin to walking into the library and asking for a book on a subject and they say we only have this one. With an extensive library you have choices and if you have a nice collection you can find something that you like and it is fun to explore listening to lots of titles that you have never heard before.
There are many artists which I have in excess of fifty titles ie Neil Young, The Grateful Dead. Miles Davis I have close to 100 titles! I will never listen to all of the music however it is easier to listen to if you have it!
