My question is about how to SEE if the AVR-amplifier was clipping.. I am talking about physical MEASURING that and not a method of trying to listen out for it. On a normal amplifier there is a technique using oscope machine to have a look, we can tune the gain until we saw on oscope screen that the wave started to become flat.. so we are able to know 100% at this point he is clipping. On AVR we only tune the volume, so can we use same technique? It seemed like most people want to listen for clipping, but then those guy insist to measure the sound with REW, so why not measure another part in the chain?

Yes, an AVR is like any other amp. You can examine at what point a sine wave starts to visually distort, clip, on the o-scope as you slowly turn up the volume bit by bit while the AVR is connected to a standard load, or you could use a distortion meter or an audio analyzer if you need a more exact reading of the distortion value as the level (and frequency) varies.

I am only thinking that audio analyzer is very expensive.. but maybe we don't really need high quality and even the cheap oscope can be enough to help the users to protect the equipment and find most power (it can just depend about equipment value anyway). In the basic technique we just watch for the wave distortion then tune back for safety, but maybe we will give up some little bit of clean power as well. Anyway I think that is still better than just by listen and guess.
