Just for my opinion,
5 > 8 > 6 > 4 > (3 , 2 , 1 same stuff)
7 is too subjective, should not be counted.
Its because the nowadays speaker can't do the job as good as the amplifier and source devices, much fidelity will be lost by the transformation of electricity to sound within a speaker.
Quality of magnets, cross over, cabinets, wires, cone and components will greatly affect the performance of a speaker.
