I expected they would say that, think about it, why wouldn't they? Integrated amp, power amp always better right? That's why manufacturer's marketing, customer support people would tell you. Reality is, one must compare the specifications, and measurements if available, before substantiated such claims.
My opinion, based on my knowledge and experience is that the 1140, when used for 2 or even 3 channel is, as I stated before, a good equivalent, toss up, with the PV7. This is based on you specific case/application.
And, as I also suggested, whichever way is more convenient to setup for your applications, is probably the "better" way. John V's good guy, I have no disagreement with what he is saying, I guess except the "integrated watts" part as there is no such thing, though I think I know what he really meant.
