Far be it from me to talk you out of doing something good for your system. Monoblocks have some advantages. The physical separation of monoblocks offers some SQ benefits. A stereo amp circuit in a single chassis has more crosstalk, usually shares a single power supply, and definitely weighs more. Monoblocks also split the heat between two chassis.
Not sure that a single chassis unit offers much benefit over monoblocks if the price isn’t prohibitive, other than perhaps that you only need one space (though larger) and one plug for it.
