Problem is, there's no way to know that unless you made the recording yourself.
The above can be said or applied to any single component or aspect of the chain.
For me, the speaker needs to be as neutral as possible (as defined by the listener). A speaker that edits is a problem.
A speaker that comes closer to being 'neutral' will allow one to hear what is ahead of it: the recordings or power or cables or components or tweaks, etc. etc.
The focus needs to be on the system as a whole, not the speaker.
