We're pretty far away from our original conversation but,
I had to break in Scansonic MB2.5 speakers as they required a lot of movement for stiff rubber surrounds. It was weeks of face to face, out of phase playing. I listened periodically and the fullness of bass (albeit a tiny speaker) did increase very noticeably. With the brand-new sound I'd have returned them. I did know of this req'd break-in beforehand. It worked as specified.
Have not had the occasion to compare 'broken or burned-in electronics as most of my gear was/is used (for cost/benefit ratio). Likewise no knowledge on for wire burn. Can't imagine tubes don't need it.
Blind and long-term listening tests both have a place for me, especially with cables and other tweaks, real or imagined.
