Here is all my gear. What's the best combo?

I feel i need some matchmaker advice. I know the "use your ears" mantra.... i have ears but also interested in advice from a tech or experience viewpoint. I won't say what' I have paired with what currently. What's your choice for best combo? and maybe what should i buy to improve that combo.
