I haven't heard or read the later SR info but it sounds completely different to what he told me when ACDC was first made. I can only go on what he told me directly. Maybe things are changed, maybe they haven't.
It seems different designers have different approaches and different answers over different periods.
I still say the Pro model is a fast playing best bang for your buck machine with any Stern title.
Play the Pro, play the LE, the Pro plays faster almost every model.
Buy what you like but as long as u buy that's what matters.
