Is there a difference in sound quality when streaming TIDAL Vs CD player

I never heard of Qubuz.  Do you need to buy a decoder to use the studio version?

What does DSD stand for?  There are so many acronyms you all use that I do not understand.  Wonder if there is an acronym dictionary?

Never heard of Red Book CD.  Looked it up and it is confusing.  Is this a brand or a standard I should look for when purchasing CD's?

For the price of tidal premium,  I'm very happy with just tidal. Convenience,  cost, selection and no cludder from empty CD cases. Just easy to take with me on my phone. Create different play list and add songs as I experience different selections. I used to be into cds big time in the 90s. This just saves me money and taking cds in and out to my car. So I believe the sound is great with tidal/blue sound. Suits my needs perfectly.  Had a great system in my truck that I sold, dont want to go that route again.  About 3k into it. 

@larry5729,

DSD stands for Direct Stream Digital (Sony digital audio format). It is a trademark used by Sony and Philips for their system of digitally recreating audible signals for the Super Audio CD (SACD). DSD uses pulse-density modulation encoding, a technology to store audio signals on digital storage media which are used for the SACD.

Red book CD is another acronym for standard CD. In technical terms, Red Book refers to a set of professional specifications for audio CD’s. The reason it’s called is very simple - They are so named because the colour of the cover of the book that contains all these technical specifications for the standard audio CD is red.

The Qobuz is another competing streaming service that is becoming popular in US (it’s a French company).

You should be able to stream Qobuz through your Apple device once you download their app. But I am not sure if you are able to steam high resolution (24bit/192khz) files through Apple TV.

When I stream Qobuz through my iPhone in my car, the resolution max out at 16bit/44.1khz (which is same as cd resolution) even though I have high resolution subscription plan.

In my home setup, I hear full high resolution 24bit/192kHz through my Aurender N10. 

None of the streaming options have many of my extensive CD collection recordings.  No Marston, Romophone, limited issue ethnic recordings, possibly 30% of my CD collection.  Plus, the source of many of my finer jazz and classical CDs can be lesser remasterings with my owning several of each with one clear superior mastering.  So, I wouldn't put all my eggs in one basket.  I have about 7,000 CDs and listen to LPs and 78s.  Again, about 40% of my 25,000 LP collection and about 50% of the 7,000 78 collection are not available on streaming or downloads and probably never will be.
