DXOMARK has quite a good reputation in objective and subjective quality testing. Although, it has to be said that this type of labo tests do not always take all product specific nuances into account. In this case for example, the technical design requirements for the portable Level are quite different compared to the Balance and B&W Wedge to which it is compared. Also quality of experience is not taken into account at all. Nevertheless, these tests are interesting to put things in perspective and to set expectations of a certain product.
I personally use the Level mostly in my bedroom at quite to moderate listening levels. Under these circumstances, for me it performs very well with a warm pleasing and accurate sound.
