I maybe do not have an overview about the high end systems available on the market, haven't heard a B&W in the 5-series or B&O so far.
But I think the KEF audio in the Emira is still decent sounding, it's no surround sound style, but a well staged stereo setup in my eyes, especially at standstill.
After my service at Sportivo Leipzig it now sounds great in comparison, they have sorted out the issues with resonating parts near the subwoofer.
I now use the following equalizer setup:
treble: -2
mids: -1
bass: +1
I really like good recorded live-sessions as you get almost drawn into the stage.
What the system does not do is sounding, a lot of average sound systems exaggerate the bass to the point that there is no differentiation possible, bass always sounds the same, 0 or 1. I find that's kind of annoying.
So in this way the sound system is very in line with Lotus, no exaggerations, no overwhelming torque but linear power when it is needed.
