I had a Yamaha RX-V650 hooked up in my house for a few weeks and used the YPAO to get the optimal sound levels. Now, my surround L speaker is a little further away then all the rest, so here is my question. With the 650 it set the level of that speaker to about +6.5 or so cause it was about 15 feet away from the listening zone and now I have an HTR-5790 and I did the YPAO and it only set that speaker's level to +1.5. Can anyone explain why there is a difference like that? Thanks in advance, I appreciate it.
