Sony PS-X5/X6/X7 line questions


I've a Technics SL-110 and Sl-120 both with an SME 3009 II arm, but also need a semi-auto for another application.

I have aquired 3 of these tables (all model X5s, and each with unique issues I need to sort) in spare parts trades and am wondering the difference between the three models.

I am aware the X7 has the carbon fiber arm, otherwise it's the same as the X6.

I am also aware the X6 and X7 feature "light touch" electric front control buttons, while the X5 features mechanical buttons.

Other than that, what differences are there between the models? The plinth seems the same, as well as the platter...
