This is exactly how sound studios do mixing. They don't just use top-end monitors -- they generally also listen on low-end speakers that color sound in a way that's representative to what people have at home (hello, Yamaha NS-10).
Many audio engineers live by the mantra "if it sounds good on NS-10s, it'll sound good on anything".
We need such a touchstone for software engineers.
You could get somewhat close by looking at what was a middle of the road consumer laptop from Dell/HP/Lenovo 5 years ago and buying one of those though.
