I thought the same about the sound system, but then I tuned it a bit with the equalizer, increased the bass a bit, and noticed something.
I can hear the creaks and finger friction rubs on guitars, cellos, and violins. I can hear the moist sounds of mouths and vocal cords from human voices. The extra harmonics in pianos are audible, where the differences between Steinways and Bösendorfers are apparent.
The sound system is less Jack Daniels and more 21 year scotch. For those of us with classical music tastes, it's actually quite good.
