You’ll have to remeasure after uploading to the AVR to see what the effect is. The creators of the automatic adjustment tool should have given such an example, in my opinion.
I don’t think I’ve seen any room correction software take measurements post calibration to show you the results.
many, including myself, have taken before and after measurements. It definitely doesn’t look as nice and smooth as audyssey but it actually sounds a lot better. I would say the approach is more “correct”, evo uses EQ to knock down modal peaks and brute force searches all delay options for best subwoofer integration.
one neat trick evo does in certain cases is lfe+main - since evo doesn’t boost, it uses lfe+main and rolls off the mains in a variable fashion so the mains only fill in the dips of the sub response. It’ll make you question what you know, believe me. If you can’t get past the prejudice of using large/lfe+main, evo also provides options to optimize in a more traditional manner.
As previously mentioned, thousands use it, a lot of comparisons have been made with Dirac and a lot of folks ended up preferring it over Dirac. If you’re skeptical, that’s fine, but try it, it’s free and has been through enough revisions that if it was gonna blow up avrs, it would’ve done so by now.
