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

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

I have a stock 5400ES and a ModWright 5400ES. There is quite a jump in sound quality from a well-mastered SACD over Redbook with the same material on the stock 5400ES. Not subtle. I would say the stock 5400ES is a good Redbook player and a very good SACD player.

The MW 5400ES is in a different league and Redbook is very close in sound quality to SACD. The MW mod improved the Redbook sound quality tremendously and the SACD quality significantly but not as dramatically IMO.

Tidal is great but sound quality is obviously dependent on the streaming gear and the DAC. It takes a VERY good music server and DAC when streaming TIDAL to get close to the sound quality of the MW 5400ES with Redbook.

My computer audio DAC is not MQA capable, so MQA titles on Tidal are a mixed bag. I find no more correlation between improvement in sound quality of the MQA version vs the non-MQA version than I find from one non-MQA title to the next based on recording/mastering quality. All MQA versions are remastered by necessity to embed the MQA packet and the sound quality of the remastering varies greatly just like mastering/remastering quality of non-MQA titles. There are some real sonic stinkers in the Tidal MQA library just as there are for non-MQA versions. Some titles sound better in their original non-MQA version.

Again, without a MQA-capable DAC, titles designated as MQA on Tidal do not guarantee a better sounding version than the original IME. It depends on the quality of the MQA remastering.

Alan, really??  I find this amazing as to my ears SACD and DVD-A are several order of magnitudes better than redbook.
