In my system it was neutral from the top down through the midrange. I thought the amp was a little bottom heavy...which many people like. I earlier owned a DNA-2 Platinum revision, which had a similar sonic signature.
The DNA-500 was transparent in the highs, therefore the quality of the highs was dependent on what was upstream.
