Trigger alert: this is a denigrating post. Not of your system, which is fine midfi, but of you.
Can't you tell if your own system sounds good? If you can't, no one can do it for you. What you're going to get is exactly what you're getting. Guys are going to recommend what's in their own systems. Some idiot is invariably going to tell you that you need some kind of Ethernet cable or box which is guaranteed to do absolutely nothing.
Do yourself a favor and go audition systems, as many as you can, until you start to discern trends and patterns. In other words, go educate yourself.
