Danoroo,
I may be able to give you some insight with regards to cables. After reading your post, it looks like you are approaching the cable issue from a purely subjective standpoint. Like you say, there's no consensus, so if you want answers you'll need to take matters into your own hands. I think I can speak for the majority of people on this site when I say this how we had to do it. And we get different results due to the variety of factors involved.
The only advice I can give you is don't spend too much money until you know what you're doing. And even then, be careful.
