BiWire Jumpers on biwireable speakers.

Too much complicated theories and tech justifications for something very simple.
... and I'm being discredited here and there, during the process. No hard feelings about it.
Please, someone have a try.

When it comes to suggestions like this, there is always going to be disagreements, theories, justifications, and demands for proof of various kinds from people who hear a difference, people who don't hear a difference, and people who haven't listened and have no personal experience but who have ideas about it. I'm sorry but that's been the initial history of many audio devices and techniques. It seems to be unavoidable. Even when we do have measurements and tests we often have disagreements about whether the results are valid, the methods used were valid, and/or what the results really mean. People are passionate about their audio and it comes out in many ways including in this way. Probably one of the few things on which we have universal agreement is that speakers make sound and some things can change that sound though we definitely don't have universal agreement on what things can change the sound.

So, simply accept that others are going to have different opinions about some of the things you do and buy and keep doing what you're doing, keep experimenting and trying the things that interest you and intrigue you. Just doing that is part of the fun of this hobby so don't let opposing views and opinions upset you. They're unavoidable. If you're into audio because you like listening to recorded music, then just go for a system which brings you enjoyment and if you want to improve the sound that you're getting—we all want to do that—try things that you think may make a difference or even ideas that intrigue you and make you wonder whether something can really make a difference, regardless of what others think about them. As Jean-Marie said, in the end we listen with our ears and we have to live with what our ears tell us. Measurements can give us lots of useful information but they don't and can't tell us everything we want or need to know. It's our ears that tell us what we like, how much we're enjoying it, and when the music is working its magic on us. In the end it's what our ears tell us the really important things, along with some other other non-measurable responses such as whether you've suddenly got a smile on your face or your foot or hand is happily tapping away on its own.
