With some recordings they don't seem to have enough bass, unfortunately. In music produced before 90 that can be resolved with an increased pre-amp. Sometimes at the begging they sounded very harsh, e.g. in Venom - Cast in Stone, because of his strong rust sounding, later I got used to it, but still they don't suit completely to such type of music, also I caught sibilance a couple of times when a vocalist pronounced "s". However I agree with the most of the written.
