Bi-wire and shotgun were the first two things I tried that convinced me to look deeper into wire. This was decades ago, back when I was using ordinary hookup wire. So it cost next to nothing to try. (Even then I was so cheap- did I really want to cut 15 ft of wire off the roll to try this unlikely idea out? Lol! Seriously!) To this day I still recommend trying the easiest/simplest/cheapest thing first just to see if it works. If the idea has any merit at all then you should be able to hear it regardless of how well its done.
But this is merely the first step. Then once you know the next is to figure out what is the best way to go about it. So once I knew cables really could make a difference the next thing was to figure out just how much and what is the best value way to go about it. In other words what you are doing, trying elevators and all these different things.
If you keep going like this, trying a lot of different things, listening close as you can for all the differences, noticing which are better and in what way and by how much, you will very soon be looking back in wonder at how much progress you have made. This is roughly somewhere between a thousand and a million times better than read/talk/buy.
