Markus, no he's not

I've used the buzz word as you put it Coherence, way before the company was formed.
Symantec's are one thing, doing the biz is another.
The ability for a system to portray the music in a totally together fashion, focused and coherent, not disassembled or out of time, or spread across the stage were they aren't meant to be.
The bass/Rhythm lines should be totally together with the rest music, NO LAG or disjointedness, the relationship between the bands players should be absolute and totally as one NO exceptions. (unless there's a solo going on

) else the system has failed in its ability to recreate the music IMO.
No matter how good the bass/treble or imaging.
The more coherent the sound IMO the better the portrayal of the music.
I'm sure Henry can put it into words better than I today.
Alex has hit most of it on the head, however I'm even more absolute in this area.
I won't tolerate a sound which isn't totally together & complete, given in a way which gives involvement and that being there Real feel of an intimate 200 blues club or a 5000 seat venue.
I really have yet to hear any 'expensive system' do this yet including some rather silly $£$£ ones.
Sure they do monster scale, great dynamics, serious bass both in extension and room filling power, with delicacy of a velvet pillow, sweet treble and life like mid band textures for sure, but that's not what its about for me
Neither is it solely about PRaT either, sure quite a few system groove no problems, yet the are devoid of the real textures, true extension and openness and detail.
The ability to portray the instruments in their own CORRECT space, not artificially stretched. and true top to bottom cohesion of sound, never favouring one section of the audio spectrum to display preference over another.
Oh its got to have involvement, which IME makes a natural appearance as the above traits materialise.
To give a focussed and integrated sound for all forms of music.
I'm very pedantic on this particular issue, and won't be swaged. T.
