@shtr74sims I have a little experience at this ;)
And I'm sympathetic to the guys who want to improve their systems. I want to do that too! And truly I don't care if guys want to spend money if something make them feel good.
But if you're interested in improving your sound, then I'm an advocate for actually attacking the problem, which is much more likely to be your listening room and source material than the quality of your ethernet cable or USB hub.
