Now I appreciate the improved imaging, especially in Trifield (amazingly better), but it does look a bit crap…
I would argue, with the latest DSP's and 818v3 (along with decent power conditioning), assuming decent speaker placement (ideally with the speakers >1m into the room, if at all possible), the 3D imaging of musicians on a stage with you sat in the audience now exceeds that of Trifield

I do, however, miss Trifield's ability at times to make it sound like you were in the middle of the performance.
