Paradigm Persona series


I'm beginning to poke around and gather opinions and information about a "super speaker" to replace my aging Thiel 2.4s.  I like the idea of bass dsp room correction and I am a bit of a point source type imaging nut (thus the Thiels).  So among other choices I've been looking at the Paradigm Persona series specifically the powered 9H with room correction for the bass.  However I'm skeptical of the "lenses" i.e. pierced metal covers on the midrange and tweeter specifically because of Paradigm's claim that such screens "screen out" "out of phase" musical information.  The technology in the design seems superlative but I just can't get past the claim re out of phase information and the midrange and tweeter covers.  What could possibly be the science behind this claim?  It just seems like its putting a halloween moustache on the mona lisa given the fact that the company is generally a technology driven company.

Yes, there is some noise from the speakers, but nothing too serious. Personas 9Hs at 96db sensitivity, I think it is inevitable.
At the other hand, Thiel CS2.4 at 87db and 4 ohm impedance, are not the most obvious choice for a SET Amp IMO.
With regard to the idea of an isolation platform I would also just point out that I'm not sure it would be desirable to raise the height of the speaker.  At my seated position my ears about 3'6" from the floor whereas the Paradigm tweeter is already significantly higher than that at about 4"1" above floor level.  That's not a problem due to the tweeter's dispersion characteristics but I'm not sure you really want to raise the level of those drivers any higher.
The Isoacoustics footers replace the stock footers the difference in height is negligible the sonic improvement is vastly better.

Also the 96db efficiency is what is causing you to be aware of the noise more than an 86db efficient loudspeaker.

Anyone know anything?
