Glad to hear it sounds like things are resolved Rob.

Now if your amp is working properly you should be able to recalibrate the sub with your receiver at or around the 0 mark on the LFE channel. That'll just give you more room to adjust if you need during movies/music. I think the +5 was more of a workaround/test to get your old amp to wake up, but the new one should not need this set as high.

Just my 2 cents, but glad it's working for you.
