What say you binding posts or direct wire?

I agree with your logic, but the same logic can be applied to every connector and wire within the speaker, and every component for that matter. Every connector and type of wire within components are subject to dissimilar metals and/or possible inferior quality. I'm a modder so very aware of all this, do upgrade wire and avoid connectors in most cases.

In the case of elimination of binding posts, not yet tried. Would require cutting into my best speaker cables, just not something I've been willing to try up to this point. Perhaps some may desire binding posts vs none, colorations imposed by bp may be pleasing in some cases.

I'm OK with my binding posts.

Perhaps not having them might make a slight difference/improvement, but there are just some things that convenience is going to win out on.

Binding posts are definitely on that list.

“I get better-sounding results just by using quality speaker cable wired directly into my networks with the same cable type after to transducer. ”

This sounds like a case of,

1) Cheap binding posts with poor metallurgy or

2) I have tweaked everything else in my system to nth degree
