Sorry for getting all up in your grill about this, Dennis, but I feel, with the 'home' users and many here who lack a certain experience with technical things, to err on the cautious side when saying stuff like that is a necessary thing.

To be honest, I have a feeling Yamaha don't go for the switching power supply thing in the 'home' market to protect their local divisions... With the internet the way it is, ordering an overseas product can sometimes be cheaper than dealing with the local dealers. This at least puts something of a brake on the practice
