I see a lot of suggestions to change your speakers. But speakers vary more than any component and are the most subjective piece in our systems. Yes I would not choose your speakers but what I like in speakers may easily not be what you like and then taking my advice would only make things worse. And that's true on any component.
Advice on any gear at best should be a description of what it does well and its flaws, not it's a great piece of equipment. Then, at least, you can eliminate components and hopefully end up with a few you listen to and make your own decisions. There is no perfect reproduction and even if there were you would have the right to pick non-perfect gear if that's what you like. I always liked the title of an article my late friend Murray Zeligman wrote called, Color Me Perfect.
