This is a very interesting discussion. My goal is to get the best sound quality from my system. Given that I am currently running my streamer with wi-fi, it seems worth considering the cabling options that many say are superior. I haven't had any problems with wi-fi dropping out, so it's more a curiosity of what I may be unaware that I am missing and optimizing this particular link in the chain.
I don't expect a massive improvement from this, but even slight improvements at this stage are very satisfying. So thank you for sharing your thoughts and experience in this area. Sometimes I feel like I may be chasing my imagination, but it is a good time...so I keep doing it!
