One thing to consider with all this equipment is how resolving are the speakers and amplifier?
I went from a Lumin U1 Mini and Pontus II to a Lumin U1 with LPS and Venus II.
I had to really strain my ears to hear that the soundstage seemed slightly wider. And I think mainly due to the LPS being added to the system.
My system at the time was driving Luxman 550AXII to Dynaudio Contour 30. (I now have Icon Audio tube amp and Klipsch Forte IV - more fun sound).
Another thing I am scratching my head about it that the Raspberry Pi 4 with Ropiee I built (with LPS) for a second headphone system into Denafrips Aries 12th sounds much better than Bluesound Node, ifi zen Stream, Musical Fidelity Stream into that DAC or the Gustard A26....how can cheep and simple sound better???
