Hi! Are there any big differences in sound and options between these models-NH1,RH10,DH1- when live recording. I am in Europe and I found out that I can't purchase NH1 anymore(at least where I am) so I am specially interrested in RH10 or DH1. DH1 is much more expensive so I don't know is it better for live recording then RH10. I am clarinetist so I will need it mainly for classical chamber music. Thx
