„By duetting with the vocal part Maria Loos showed a capacity for understanding and the ability to listen exactly. She cast a colourful spell over her listeners with fine dynamic shading and a phenomenally clean intonation. She played enchantingly with precision, a highly imaginative ability to ‚decorate‘ the music and a dazzling wind instrument technique. Handel’s sonatas appeared fresh, as though they had just sprung from the composer’s quill.“
