For me, the best classic Hammond sound is, as often described, "throaty" rather than bass heavy. You don't always get this with all combinations of classic consoles and Leslies. But, when it is there, even on recordings, e.g. Bill Champlain, it is wonderful "glue" even on simple comp chording in a full band context. I wouldn't want a software update that increases bass note loudness if it is at a cost of less "throatiness." Is it related to smeared sound? Perhaps.
