I'll suggest keeping the generic HDMI for now. You'll find that most of the expensive HDMI's don't really change that much.
What options does your dealer offer, and what's your budget? I generally feel a system with good interconnects and power but generic speaker cables sounds better than good speaker cable with generic cable throughout the rest. You might also want to consider putting a large chunk of your budget on power filtration if you haven't already.
