Shadorne - all the sliders on those mixing tables are most likely level control. There are also, as far as I know, Equalizers but extremely expensive (for a reason). Typical tone controls in home amps use pots with very poor matching.
As for not caring by the artists about sound - many of them have their personal sound engineers for recording that replace one in studio wherever they're recording. Home system should replicate exactly what was recorded and not to improve it. Fixing shortcomings of the system or the room with tone control is a bad idea.
