I wouldn't say that if your goal is less expense go integrated amp anymore than I would say if your goal is more expense go separates.
You misinterpreted my meaning. "Less expense (via fewer ICs, power cords, power outlets)". You can save money by installing fewer ICs, power cords, power outlets, dedicated lines, etc. That equates to less expense for ancillary equipment. I did not mean less expense because integrateds are cheaper.
