I got a chance to briefly listen to the Paradigm Prestige. The local dealer just received a pair of 85Fs in Piano black. I think the exterior finish and shape, with the plinth supporting the speakers look much nicer and higher quality than the Studio line and they sounded pretty darn good. As for the looks of the drivers, I guess you either like them or not, but who cares if the grilles will cover them anyway. Speaking of the grilles, this is where Paradigm cut cost. They are very cheap plastic, but you could only tell if you actually held them. The 85Fs are actually not as big as I thought they would be, about the boxy size of the B&W CM10s.
As for the sound, based on my limited listening time, they are not as detailed (i.e. bright) and airy as the Studios, but rather laid back with excellent soundstaging, and a sense of fullness in the sound, not as lean sounding as Paradigm speakers can be. There is cohesiveness in blending of the highs and lows, with impressive bass quality, leaning more to the warm side of neutral, which I think is a departure from Paradigm's detailed and neutral sound over the years. I think folks will either like them or not. You just have to listen to them and judge for yourself. My dealer said they lean more toward the warm sounding speakers like Sonus Faber. I sort of agree. He said he has already sold several pairs and thinks, given the price, they are stealing sales from the Signature line.
