"Wire INSIDE the laminations behaves differently than wire OUTSIDE the lam-stack."
That can mean a lot of different things.
WRT the resistive losses, inside or outside it's all the same.

I don't want to take a position in the debate, because I don't feel qualified, but is it not fair to say that the impedance of the wire inside the inductor is very very much more reactive in nature, compared to the wire that comprises the leads, made so by the fact that it's coiled? I think that's all Tube Wrangler meant to say. Yes, WRT its resistance, there is no difference between wire inside vs outside, but TW would advocate low DCR inside and low gauge outside, so as to ameliorate that factor as much as possible. The wire inside, however, is there to create inductance specifically. Just a thought.
Maybe there are paramagnetic/diamagnetic effects to consider here. Based on my limited knowledge of this subject matter, I'd expect the effects to be infinitesimal. OTOH, perfectionist audio revels in the infinitesimal.
read the marketing claims of dennis...that will tell you all you need to know. His amps sound different...maybe you like, maybe you won't...but that is up to you if you like his brand of different. The wording of the claims is all the proof you should ever need...LOL

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
The wire inside is of course interacting with the magnetic field it is wrapped around. This does NOTHING to its resistive properties. If there is nothing wrong with this stuff, why not just use it for the lead outs? Eliminate a solder joint, eh?

I've run across vintage chokes and PTs "terminated" in the very manner you describe: the enameled magnet wire becomes the leadout with the addition of insulating spaghetti. And I always thought this was a money saving trick.
The older style ElectraPrint transformers are done this way for the secondary.Edit, I should say apparently done this way. The lead out wire is solid core, enameled magnet wire.

It is quite possibly a cost save...:) however, since it is claimed replacing the lead outs helps, and that the coils in the bobbin are perfect as is, using said wire for lead out follows naturally IFF the scheme has any merit at all.
and btw, make the Benz a 6.5 and I'll take it v. the bus anytime...maybe followed by a 115-body, 'C' with a manual and an OM617 under the hood...:)

I didn't mean to imply anything more than what I said.
The same as you said. "Yes, WRT its resistance, there is no difference between wire inside vs outside".
