I own the Technics SM-ZS30 about 10 years and I am very satisfied with it's performance. Because of my impaired hearing and bent fingers (DuPuytren)I have given up playing and the Piano (Bechstein) to my daughter. I can't find the User's Manual and I would be glad if somebody could send me a copy.
I remember the manual as very clear and usefull
The sounds are very nice
I had the equipment installed by a german piano technician recommended to me by Bechstein Berlin
