Does anyone here have any hacks for the Yamaha DVX-S650 or DVX-S150 home theater system????? also does anyone own this system, and if so what are your experiences with it good or bad?????????? I want to purchase it but would like to know some opinions about it. If I do decide to purchase it is a used model that is missing the YPAO (Yamaha Parametric Room Acoustic Optimizer) it is some sort of antenna I would like to know if anyone would be willing to sell me there's if you do not use or need it anymore. Any help about this system would be very appreciated.
