Here the definition of "accurate" is: the inevitable price and size constraints, the tone and color reproduction, dynamic and environmental aspects of the details of the original recording in the frequency range of the widest possible, change as little as possible. Of course, this definition is also roundabout, indirect, because if you do not use a speaker to play out, how can you know what it was like the original sound? If we choose an artistic record, we should assume that it can be reproduced as true as it is. Although the recording equipment (such as microphone) in the inherent quality with the speaker as there will be differences, but the real difference between several excellent sound recordings on far more than the difference between the speaker should be a good and a mediocre much smaller.
