Mids: Clean, natural, and coherent. The GL-6087 favors a midrange free of veiling, with a smooth and accurate presentation of vocals and acoustic instruments.

Highs: Extended and uncluttered, never harsh. The high end benefits from a smooth, noise-free power supply, with refined and stable reproduction even in the most complex passages.

Dynamics: Excellent transient and load handling. Response is prompt yet composed, giving a sense of total control over the power supply.

Soundstage: A stable and well-anchored soundstage, with a perception of greater depth and spatial coherence. The GL-6087 contributes to an orderly and credible presentation of the stereo image.
