Usage

Can be used with either な or の as a modifier: 良質(りょうしつ)な素材(そざい) or 良質(りょうしつ)の素材(そざい) (high-quality material). Both are natural, though な is slightly more common.

The opposite is 粗悪(そあく) (inferior quality) or 低品質(ていひんしつ) (low quality). Compared to 高品質(こうひんしつ) (high-quality), 良質(りょうしつ) sounds slightly warmer and less technical.
