@SONICFANTASTIC:
Thanks again @blisshifi for the explanation and the two factors you raise are imaging of the sound towards more life like and fatiguing peaks which I assume tends towards the higher end of the frequency response. Are others hearing these differences as a result of a streamer change and not related to dac or speakers? Or have you had the experience where the streamer does not not appear to make a difference? How expensive did your system need to be to hear this difference? Did you have lower cost systems before where you could not hear the difference?
I will state that the addition of a separate streamer (Auralic Aries G2.1) made an obvious (to me and my listening companions) improvement to the sound of my Tambaqui DAC. Do you need a resolving system to hear this? I suppose, but it was not subtle on my system. For Fantastic Sonics :) it is needed. I added the separate steamer (I have Roon Nucleus+ in separate room) in front of the DAC.
I can hear this. I also heard the improvement with a Networks Acoustics Muon Filter and ethernet cable.
