Yes and No, before I ran YPAO on my new RX-A4A, I ran though just the settings I needed to get that AVR up and running.
No internet connection, No DSP settings Nothing just two channel with speakers set to full for 2.1 use only.
Out the box it was amazing sound! later on that day I decided to run YPAO for movie use. Wanted to try out A.I. Well I got mixed results.
All though, A.I. use did create a 3D envelope sound field with a 5.1 setup. The low end was sucked out lacked the punch it had before I ran YPAO.
For a long story short, No YPAO isn't as good as I thought, I wouldn't recommend using YPAO. Do Not even run the ARC at all. Just use "straight" setting. use a tape measure that will Not collapse over 10 ft pull your own measurements from your main seating position. Than use a sound pressure level meter, dial in your levels, set your distances and use sub trim if need be. Find the drop-off of your speakers main left and right snd your center channel.
Your rear surround/s do the same.
Untill Yamaha can get YPAO right? I'll never run anything of Yamahas ARC again.
