Glad to hear things worked out. Usually YPAO errors out if the sub channel is at -10db. I would turn the knob down a little more on the Cleanbox, that could help with the noise floor. Run YPAO and make adjustments to get around -7db on the sub channel. The multi point measurement will most likely run the subs hotter, at least that is the case on the A3070. The boost could make it sound boomy, hard to say what is happening at the MLP. I would know it down a few db at a time and do some listening. It is all very subjective as to what sounds best to you. My subs get boom when against the wall, moving them a foot out fixed that issue.
