I don't entirely disagree - in too many orchestras the bass sound is weak compared to the higher pitches. Has a lot to do with the orchestration, but Brahms and Mahler, just to name two, were really concerned about the bass sound and that's why they used bassoons, contrabassoons, tubas, and basses so much. But in some orchestras you have a real mismatch. In a typical small orchestra string section, numbers like 8-8-6-6-2 is common, but it should be 8-8-6-6-6. Those bass lines are so important. One conductor I work with gets it, and frequently has me playing contrabassoon along with the bass section where a rock-solid, loud bass is needed. Adds immensely to the 2nd movement of the Beethoven 7th.
