No bearing on sound quality. Not like tube vs. SS amps and preamps. Overall design and quality of components is what matters here. Actually, the nuvistor has characteristics of both a tube and a transistor...sort of a cross-breed.
I know of a tube guy that recommends staying away from anything with nuvistor "tubes", due to possible QC tolerance problems involved during the manufacture of such a tiny pseudo-tube.
