YPAO volume (adaptive eq) can help you crank it up less and help retain what little of your hearing you may have left!
On Yamaha receivers, when you turn YPAO volume on, it also turns on "Adaptive DRC" as well by default. Adaptive DRC may be the reason most people think this feature sounds like ass. Disable Adaptive DRC and use YPAO volume on its own. It actually is a very useful and nice sounding feature imho when you're listening at lower volumes.
YPAO volume saves my marriage from time to time.
P.S Don't let a receiver do parametric eq automatically. TREAT YOUR ROOM and do the parametric eq manually. Yes, it takes time to get things right. There's no quick solution in this business.
