Non-feedback amplification topology and frequency

Is it true that non-feedback topology amplification is prone to frequency limitations if not matched with the absolute perfect speaker system?
I'm trying grasp how to get a flat sound from my very much loved new PL5. I have resorted to EQ, that never mentioned term on these forum, to bring back the ultra-highs of cymbals and bells etc. I've also rolled the pre-tubes and switched out my ICs. Still very much a frown freq graph.
I'm willing to get new speakers to help this amp deliver on its promises. Focal seem nicely high in sensitivity.

Atmasphere, is it so that a non negative feedback design does not have any odd order harmonics? If that is not true where does that leave us? I highly respect your dialog on this forum and I don't want to stop it so my question is a sincere one. I wonder if we are making too big of a deal with NFB in high quality amplifiers. If the overall design of the amp needs minimal NFB how does that in real conditions compare to a non NFB design. Isn't that a competent design then no matter what emitter device is used? Then I don't think we are talking about bright and harsh as noticeable differences are we? Arn't we really talking about competent designs and non competent designs then? Thanks again Atmasphere for your dialog.
