As a matter of principle, it seems to me counter-productive to seek to evaluate a component using other components of a poorer sound quality than the one under evaluation.
But it is more counter-productive to seek to allocate reliable or universal relative sound quality ratings to diverse components.
So the answer is not 'no', but 'the question is not susceptible to a reliable answer'.
