That's the thing , there is no setting responsible, because if the data streams are identical on output...then nothing has been gained or lost.
That would be true. But what if the audio data path doesn't deliver identical data streams?
Consider;
Spotify ==> Spotify App ==> Windows 10 ASIO/WASAPI ==> DAC/Sound Card
vs
Spotify ==> Fidelify App ==> Fidelify ASIO/WASAPI ==> DAC/Sound Card
vs
Spotify ==> Spotify App ==> [Direct Sound mess/decoding/re-encoding...Don't know what happens in here...Windows 10 ASIO/WASAPI] ==> DAC/Sound Card
Then there could be a real difference in the data stream delivered to DAC/Sound Card, couldn't there?
I haven't used Spotify yet, so I don't know what the output options are, and whether Direct Sound gets into the mix at all. But if it did, there could be a real sound difference.
Glimmer, how do you output from Fidelify and get it into MC? Do you use the WASAPI loopback capability or something, to feed the Fidelify WASAPI output back into MC? I haven't played with those capabilities yet, so would be interested to know.
Or are you in fact using the WDM as output for Fidelify? You could do that for Spotify anyway using the official Spotify App if you set up a Zone for Spotify playback, because lag would not matter when just playing music from Spotify. Fidelify is still in Beta, and hasn't had an update in over a year. There isn't much activity on their forum either. So I wouldn't want to be relying on that App.
I am not using room correction or any DSP.
So what you are saying, if I am hearing a difference either it is all in my mind OR there is a problem with general set up (not using JRiver)?
If you are noticing a really big difference, and you aren't doing any DSP in the audio path, then there is probably some other difference in the audio path, such as Direct Sound doing conversions.
If you are just hearing colour, depth, breadth, timber, warmth, stage, or other features you prefer more, it is probably all in your mind.
