I watch a lot of YouTube videos regarding hifi and a few times I posted my problem with having different DACs but never hearing any difference even with some costing many hundreds of pounds. After many posts, Mark at Elite Audio contacted me with advice and a solution using an Ethernet filter to block out the background noise associated with digital signals. Mark even posted out a loan filter and a 7 port Ethernet splitter plus the cables at no cost to me and it worked amazingly with the sound exploding in clarity and a very wide soundstage, bass very tight and precise and the vocals coming right at you with the sound enveloping you. I was totally gobsmacked. I can now hook up all my Ethernet equipment hard wired which is so much better than Wi-Fi. Can't thank them enough for the perfect solution.
