HardPoint was designed with the clear goal of not compromising the sound or altering the tonal balance.

What it does do, as you can read in the review, is help the sound projection achieve more focus, clarity, and better harmonic density. 

The decays and delays that are critical to recreating acoustic space are denser, and the perception of higher resolution allows for a more open and naturally relaxed sound that is not dynamically constricted.
