I've been a happy user of an Alpha 9 integrated amp for a few years now (I've an Alpha 9 CD too), but wonder from time to time whether it's worth splashing out on a 9P to go with it. Does anyone have any recommendations - should I take the plunge? If so, where's the best place to pick up a 9P? Ebay, I guess, right...? Thanks in advance from a newbie!
