One of things we have all learned over time is that cables, dongles, filters, switches, linear power supplies, switch mode power supplies, power conditioners, power cable, dedicated lines, etc etc etc...they ALL do something. Device A with cable B and power supply C, when combined, make an amazing difference. Device D with with dongle E, when combined, sound amazing. Then, like we all HAVE to try....we combine Devices A, B, C, D, E and presto! It sucks.
There is no substitute for trying and there is no guarantee that if one is good five are better. Try things, make notes, decide if you like it and then, if its worth it. From some of the photos I’ve seen of some systems, if you tell me my room has to look like some of those rooms to get 2% more performance, I will pass. The most important thing, have fun and enjoy your music.
