I have a RX-V465 running all energy rc-10 with a Polk audio old sub. My question is when running the ypao testing the eq sounds a lil dull. It lowers the highs so my speakers don't sound crisp. I then reset the eq (all frequencies at same level) it sounds so much better. Does the ypao do a good job on eq settings or should I use something else to calibrate frequencies on EQ ? Experts pls help I want to calibrate it best as I possibly can.
