Sabai, I recall you working with the "series" concept a while ago, and I sincerely applaud your creativity and persistence. However, I feel you are disadvantaging yourself with this method. For every change achieved by adding an unnecessary interconnect to the chain, and an unnecessary connection, you are also losing information - you are gaining tonal variety at the expense of precision.
My perspective is that whatever goal could be achieved with the series method could be achieved better by selecting proper cables not in series, but if desired by mixing them. If you feel a particular cable sounds thin, then you place yourself at a disadvantage in using it at all. You are merely degrading the end result in order to adjust the thinness. That is not something I would recommend for the reasons I have stated.
I'm not under the impression that I will change your mind in this matter, but I'm sharing my perspective based on use of cables.
