Typically you will get a “wow, that sounds better’ every time you double the cost of the component (single function box like streamer, preamp, DAC, etc.) But you just can’t buy component, you must do your research and get the best of class and one that caters to your tastes (detailed vs musucal for instance). I have experienced this really great improvement since the average cost of my components were $200 to now fifty years later where the average cost of my components is $20K. Yes… it goes on forever.
Having said that, it is also a function of all your other components. Unless they are not resolving and problem free enough you are not going to hear much of a difference.
Looking at what you are running right now… maybe you will hear a difference maybe not.
I have to ask. Do you not hear a big improvement with the Cary?
