I'll refer, with your kind permission to your HT system only. The rest doesn't worth the effort.
I've told you what cable you need. I took the time and the effort doing so.
If you have other ideas, you are welcome. I won't take the responsibility for that. I do not understand why you would ask for my advice and then do else. Is that sounds right to you?
Well if you go your way, it is your choice. However, it would have nothing to do with my thread. This is not a bi wire thread and I do not wish to keep that subject as topic here.
It may not benefit any of us.
