You had trouble with the cards didn't you Greg...?
I have read a few times where the card type system has had its glitches... which is not cool... too much stuff moving around? Improper alignment?
The one Im looking at is not... its pretty much identical in layout to the Rotel or any other A/B 5 channel amp.. 1 big huge torroidal PS instead of the idividual ones on every card... as well as the multilayer heavy duty traced boards...
I am hoping that will make a difference towards reliability...
