When I moved to a new apartment a few years ago I decided to get a 5.1 home theater system. Wharfedale Diamond speakers are quite nice so I decided to get Wharfedale DX-1 home theater. I have been pretty happy with it except for one major annoyance – the amplifier inside the subwoofer tends to break when I move the subwoofer for cleaning.
I changed the TDA7294 chip the first time this happened, but now I think that I will get a class D amplifier module from China and use it instead. I will post some pictures when I complete the mod.
