Let me take a whack at this. I have a family member who had a 5.2 Ohm system with reasonable AB amps and run of the mill DAC. Big Ohms in the front and smaller Ohms in the back. That system in either 2.2 or 5.2 formats excelled at presenting music with accurate tone and dynamic impact. And it could be enjoyed in anyplace in his large listening/living room. While there was a sweet spot, especially in 5.2, every place sounded pretty sweet.
But the kind of spatial definition and seemless placement of instruments you get from excellent dynamic drivers in two channels in a traditional listening “sweet spot” just was not there. In contrast, you felt like you were inside the performance - perhaps more like a live venue. Piano music sounded fine, but not remarkable. Perhaps better electronics and cables could have helped there.
He moved and sold all that gear and replaced it with a Focal/SVS 5.2 system powered by Emotiva electronics. Same basic cables used. This system is more resolving, with the spatial definition that I have come to expect from Focals. Piano music is convincing. Good recordings of classical, jazz, country or alternative are breathtaking. The deficiencies of most pop and some old rock recordings are exposed in the glare of accuracy.
So, my experience was that the Ohm based system presented naturally throughout a larger listening area, and was more forgiving of poor recordings, while a Focal system was more incisive but less forgiving. I find both enjoyable in different ways.
