Upgrade from Paradigm Prestige to Persona

Hi,

I need some advice and guidance please...

I have Prestige 75F fronts, 45C, 15B surrounds, SVS SB16, and 7 Paradigm Millenias as surround back and heights. All powered by Denon X8500H.

I am considering upgrading the fronts to Personas, but I have so many questions in mind... For better music quality...

1) Is the difference in sound quality worth the investment? Am I going to be blown away with the upgrade from the Prestige? Note: I never got the chance ti listen to it... No Persona dealers in my country, I will have to import it.

2) If I upgrade the L/R “only” to Persona, would they still work well together with the remaining Prestige/Millenias for movies? Can I postpone replacing the center, and keep the Prestige 45C for now? Until Paradigm releases a small center Persona ;)

3) The 5F is so appealing to me, but the 3F is much more gentle on my budget. How would they compare together? Is it just a little bit more dynamic range and lower frequency, and that’s it? Or there might me other quality enhancements? Would the 3Fs paired with a decent subwoofer compare well to the 5Fs? I assume the 3F with a Sub2 would outperform the 5F in every possible way... Note: My budget doesn’t allow for 5Fs + subwoofer.

After I decide what I will do with the speakers first, I will have to think about upgrading their amp, and maybe consider a stereo preamp as well.

Thanks in advance,

Seif
