It could indeed be some kind of hard reflection issue, but it does look a little too drastic. If it was me I would like to double check the validity of the results, for example, try alternative analyser software, maybe even try a different microphone. It is just possible that the mic or software is the culprit, maybe not, but it is at least possible. Also, if I could beg steal or borrow another dac / amp combo, I'd repeat the test without the Devialet. (Maybe you have a surround amp, that could provide a substitute in stereo mode?). Loads of hassle I know, but if you could try any of the above, then you would genuinely start to have some real evidence for what is occurring.
