There's literally an ocean of different ethernet cables out there, at various price points. And, if you ask what peoples opinions and preferences are in ethernet cables on a forum like this, you're subject to get a thousand different answers. However, at the end of the day, trail and error in your own audio system is the only way to know for certain what sound best in your own audio system. I have found that soliciting ideas recommendations from others can be quite useful and fun. However, at the end of the day (as you probably already know), trail and error is the only way. Happy listening.
