Digital streaming/library


I have purchased a rather substantial 2 channel audio system, and two of the components are a streamer and an audio nas...a melco. I want to build a digital music library. I would love to have the hd level tracks, but the downloads are so expensive. I already have thousands of lps, and thousands of cds. I have iTunes, and it (and rhapsody) allow you to download tracks into your computer...but they are not cd quality. I have a streamer, and I could get the tidal or deezer hi res subscriptions, but do they allow you to download tracks into your computer/nas drive for a digital library?

easola01, I would check first if you can hear any difference between formats.  In addition, many high res files are just 16/44.1 up-sampled.  They end-up with more bits and higher sample rate but don't carry more information.  My DAC up-samples data anyway.  I also have thousands of CDs that I keep on external hard drive in ALAC.  I Wi-Fi them to Airport Express that feeds Benchmark DAC3, using ITunes.  With this scheme I'm limited to 16/44.1 but don't have to worry about anything related to computer (speed, playback program, amount of memory, electrical noise etc) since my DAC always gets bit perfect 16/44.1 data.
Get Roon and Tidal. Enjoy your private collection and an extensive streaming library at the same time...

Make sure Apple Core Audio (audio midi setup) and Apple iTunes are both set to 16/44.1. Core audio is a terrible SRC converter but the one in iTunes is good. Avoid at all cost any Core Audio conversion.
Shadorne, I thought I checked it but it was long time ago.  I will check again.  Thank you.
