Hi, got a bit of a dilema. I have a cd8se and psx-r, but yesterday i got a pre and 8 power amp and another psx-r is on order. Was wondering if i got another 8 power instead of the psx-r (nearly same price), and used them as mono's, would that be better than the above system, or would it just be louder? Eventually i would get the parts that i dont go for just now, but want the best set-up possible for the moment.
