It is easy to troll people who are in a rush to prove what they know, especially if what they know is not a lot. If this is a troll, a lot of effort has been put into it. The poster has system pictures with many expensive accessories.
The best example of this is when I was running Audioengine A2+. Those are tiny and needed far less power. Those were also running on the Palladian. The power main was the Shunyata Research Delta. I felt the sound quality was incredible, except a bit thin because of the size of the drivers. I upgraded to the HD6 with the expectation that it would sound better than the A2+.
The first clue should be the $699/pair, powered speakers, that makes up the reference system. Most should have checked out at that point if they didn’t check out from the insistence that those most likely to be able to answer the question don’t answer the question. Expert troll or begging the answer or just confused? Either way, it has sure brought some people out with some very curious ideas of how electricity and circuits work. I find it entertaining.
Concerning the mixture of various answers in this thread, I feel like they all counter each other. On the one hand, saying that the type of conductive material doesn't matter, but on the other hand saying you need more conductive material. 🤔 Then suggesting cables don't make a difference, but getting a bigger cable is best 😏.
Okay, I will play along just for fun. If you insist on only getting answers from people who don't have the knowledge to answer, why are you surprised that the answers are all over the place. People with the appropriate knowledge will all respond the same. People without the appropriate knowledge will be guessing and their answers will be all over the place.
