I have two Denners, an olive wood and a pallisander. The pallisander definitely has a fuller sound than the Olive; it also has a stronger low F. That said, I just compared the low notes of those two and the Rondo (maple) and I don’t think the Rondo is significantly softer. The big difference is that the Rondo tone is cruder. In either case I don’t play in an ensemble so I can’t speak to the Denners effectiveness there, though they are advertised as being suitable. I do play duets and they go perfectly well there.
