Super useful for those of us who rely on a good stereo image for in ear monitoring, or playing at home through stereo monitors. Fractal products have this and it makes a massive difference.
an additional benefit here is this block would remove the need entirely to use up a parallel row on your grid before your output to create a panned stereo output, thus freeing up a heap more options for other parallel effects.
An even easier alternative would be to simply have a ‘width’ parameter control that does this with a cabinet block automatically. Essentially turning this up duplicates the mix IRs LR with a stereo enhancer effect.
