I have not tested 93, but probably 15+, and on some of the DACs I own, I would call the more technical ones, there is no difference, unless intentional. On some of the DACs I own, enjoyable, designed for a certain presentation, but not "technical", they are more impacted by the streamer. This all makes sense once you understand what is happening.
How much difference in Sound quality can be expected from different streamers?
I would appreciate very much in obtaining advice on the SQ from different Streamers. I am currently using a good quality vintage DAC (Altis Reference) connecting to Roku 4 (using its Tosslink out to a simple coaxial converter which connects to the coaxial “in” of the DAC). When comparing the SQ of the exact same artist/music through first CD setup( CECTL0 connecting to the DAC) or second setup (Oppo 105 to DAC) vs ROKU 4 accessing Tidal Master level at 48KHz, both CD systems provided better SQ with CECTLO the best. I was reading with interest on the forum (4/2/2021) on DAC and found out that the SQ from different decent DAC does not appear to vary too much; the new DAC may offer connection convenience, but not necessarily SQ. More likely, different CD player or Transport can provide a more obvious difference in SQ than different DAC, like what I had experienced. Thus I am very interested to seek advice from those who had experience in comparing different streamers. Can high end streamers when accessing Tidal Master level produce much better SQ than Roku 4 if connected to my DAC(at sampling rate of 48KHz)? If so, which ones would you recommend?
