i think the UI argument, while rational on the surface, is a specious one.
there are two types of Meridian installations (even more so with 800 series equipment).
1) professionals install the whole thing or
2) ultra-geeky consumers install the whole thing
in either case the UI is not an issue. the "average consumer" isn't buying 861s.
i'm a happy 500 series owner but bemoan the insane redundancy between my 500 series units and the lack of configurability of I/O. since i use DSP speakers, all the analog out stages are nearly worthless. the duplication of functionality b/w the 568 and 562V.2 is excessive.
but i can't justify the substantial cost for the 861.
HOWEVER with a room correction card (and boy does my room need correcting - the LCR speakers are one on a floor one foot higher than the listeners; the center of the ceiling is open to the floor above; wall of stone; wall of glass; you get the idea) i'd be all over it. it'd be worth the entry price.
i've looked at the z-sys stuff, but i'd rather Meridian just did it right, fully integrated and pc controlled.
i agree with healthnut that we'd all probably fail double-blinds on most of the stuff, but room correction we'd know spot on.
so, what's the story, Meridian?
