I had the v2 version of that exact receiver years ago and compared it to an older Yamaha model (the 667 I believe); the Cambridge definitely had more power under the hood, but that only matters if your speakers are inefficient and/or you crank it a lot. It depends on the room, but I find YPAO does a good job and can also be customized which is nice. The downside to it is that it doesn't EQ the sub, but since you have a 8033, that doesn't matter so much. I would also look at the Denon 2313 which uses Audyssey MultEQ XT. Get both and compare too see which one does better in your room.
