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

Your saying stream and not worry about SACD's or CD's? Are we talking SACD quality or CD quality?

Forgot to ask, I take it a good DAC will have to be included in my system and what model, brand would you suggest?

I’ve been looking at some SACD players, but if you want multichannel, there aren’t too many options.  I liked the classic XA5400ES for multich, especially since my pre/pro could do DSD over HDMI.

However, with the ability to just download DSDs, I think the best way to do it is to just download them, getting a bit perfect copy, and use a multichannel DAC like the e38 or a surround pre/pro that can accept multichannel DSD input. It’s getting real tough to justify a dedicated multichannel SACD player if you can get the few decent multichannel DSDs directly. 

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.
