I have a local dealer that had the persona 7f in his main listening room for 2 years and every time I stopped in the components were different and so was the speakers presentation. Having never heard Tekton or Canton I can't offer any advice, that said, The better a speaker's made the higher the ceiling, duh. Many brands match speaker pairs to .5 db of each other also using matching layers of veneer. Speaker manufacturers that reach that level of competence that can afford to invest in equipment to insure product consistency like Canton, Dynaudio, Revel, Kef, B&W, etc often have a very high ceiling being limited by the components and our own ignorance matching speakers to rooms and placement.
I've bought and sold many highly regarded speakers (2nd hand) dissatisfied that in hindsight I can concede my components were likely the cause because 'budget components and TOTL speakers are a crapshoot. I seriously doubt Tekton has as high a ceiling as Canton or other Major players, but for plug and play systems I expect Tekton is the easiest to get good sound from because they're amplifier friendly and play with plenty of dynamics while our big brand speakers suck our Anthem/hegel/parasound amps (speaking for myself) dry.
