I would suggest if you are interested in objective views based on facts and data, read more online reviews that include bench test measurements, instead of subjective views. It is not a rule that AVRs are only good for movies. AVRs can be better than integrated amps in specs and bench test measurements, but the reverse can also be true. So again, those who made such claims in a general statement form is simply spreading hearsay. I would also suggest you don't take part in furthering such false claims (false if stated as a general statement, or a rule), and instead focus more on objective views based on facts and figures.
Those who have responded to your question so far also own separates and/or integrated amps, not just AVRs. So we based our opinions on specs (we all tend to read a lot..), bench test measurements, and our own experience accumulated over many years in this hobby. If you are interested in objective views based on science and technology, and specs verified by bench test measurements, you have come to the right place. If you are more interested in, and tend to believe in subjective views then we (me anyway) probably can't help much.
