Although I've posted this before, this is an apt thread for it. I don't really stream except playing my downloads from my computer and Apple Music on the computer. I have an ifi pro idsd dac I got used and added an Iris DDC (though I'm selling the Iris to upgrade to a Hermes).
I got a T+A Dac 200 in trade for an integrated amp I was trying to sell and then added the Aurender N200 streamer after reading all the comments about how good streamers and the Aurender were.
I was able to set up both systems to quickly A/B them because I agree and know that audio memory is very short. So I could almost immediately switch between the 2 systems.
The Aurender/T+A set up had slightly a slightly larger soundstage and a bit of a digital glare. This is a system that was essentially $12k more expensive than my usual system. I switched back and forth numerous times and could barely hear any differences other than what was mentioned above. I sold both the Aurender and the T+A taking a bit of a bath but regaining most of my ill-spent funds.
The Iris DDC added much more to my system than the Aurender or T+A. I am going to try out a PS Audio Directstream Mk1 that has been slightly upgraded to see if it is better than the ifi plus I can try an I2s connection to see if that is significant. The Iris had to go only because it's I2s connection is not compatible with the Directstream thus the reason for the Hermes which can adjust the pin setting and the Iris can't.
So right now, you can say I am a streamer skeptic. Plus I didn't hear any added benefits with using Qobuz or Tidal which I did a trial of each.
