Mark covered it well, for a change. (j/k Mark; you know I love you).

I use a surge suppressor. I'm pretty sure that - if my receiver thinks it has enough electricity to work - I'm not going to be able to hear any difference in sound quality.

I buy the higher-gauge HDMI cables from Monoprice, because they're still really cheap, and it makes me feel like I'm doing "something". Plus, I mostly like to get the 10' ones because I just hate cords that are "too short".
