I suppose they could move toward toroidal transformers although I don't know whether that would reduce or eliminate the hum. In my case, the unit sits in an enclosed 'hutch' entertainment unit that has one end open to the air when in use. The transformer hum that I noted above is no doubt amplified by being in such a cubby, but it's also not hearable when a foot or so away so unless it gets much worse I'll probably never pay attention to it again.
I can say without a doubt that the Vidar/Saga combo sounds superior to my Yamaha A-S801 and Cambridge CXA81 that were in the main system previously. I'd guess it would take a LOT more than $1000 to beat them.
