Should I buy SACD's or Buy Quality Multi-Format CD player and use Old Digital CD's?

As much I love the convenience of streaming over Tidal, I still very much enjoy spinning my SACD’s and 24bit HDCD’s. 

It really boils down to one’s personal preferences. If you’re shopping for a player, Oppo UDP-205 with a very decent internal DAC to consider. 

Like it or not, HiFi Streaming and High-Rez downloads is the way forward. 

+1 for Tidal Streaming.  As was mentioned above, Tidal offers uncompressed albums whose sound quality is excellent.  You search for your album, and if you like it, make it a favorite for future listening. Tidal Streaming offers playlist selections for jazz, classical, folk, blues, etc.  You can build your own playlists and Tidal also offers 500+ MQA albums. 

I listen to Tidal Streaming most of the time fur its musical selection and sound quality.  Tidal does not have every album in its library but I can easy find something I like. 

Since your source is digital, you are going to need a DAC to convert the digital signal to analog.  Pricing for DAC’s range from $99 to $20,000+.  I do not know your equipment or budget.   For example,  I own the Ayre Codex DAC $(1,995) and it sounds excellent.  Schiit has received good reviews and they make several DAC’s priced from $99 to $2,395.  Mytek also makes several different DAC’s.   You have many DAC’s available for you to consider that have many different features, capabilities and prices. 

I do not know. Maybe you should buy the Bluesound 2 Streamer that includes a DAC.  The good news you have many options to choose from to meet your needs.  Have fun.    

As I mentioned above, Additional Bluesound Vault 2 info (this is background info on one of many options):

Just as a note, I have a regular CD player (beosound 9000) but I’ve supplemented it with an NAD M50.2 digital player. It can rip my CD collection (2 TB, in a RAID mirrored setup) but also links to Tidal (and decodes MQA to 24/96) and downloads my purchases from HDTracks.com. Both players are connected to the DAC on my pre/pro (emotiva XMC-1, burr brown DSP).

I was going to get an SACD player, but I went with the M50.2, which I thought was more functional.

I will admit that I’m a little annoyed that DSD support may not come for this device, but as a ripper/streamer, it has 90% of the features I want at a very reasonable price.

I have never found sacd's to sound better than redbook, and I have a Sony 5400ES. 99% of the time I stream from Tidal, the sound is great with over a million albums. and lots of MQA files, over 3000. They only list 500 but there are way more
