1oldguy;
Well it sounds like you might be starting to like the equipment as they open up. You might already know the following, and I am sorry for repeating them here, but it might help you.
1) Your bass output from the 802s is to some palpable extent dependent on how long and how thick your cable run from the 7Bs to the speakers. The cable runs should be as short as possible. The cables should also be as thick as possible. Thick short cables provide lease resistance to the amp, resulting in appropriate delevery of current to the 802s. This might be overkill, but for my 804s, I used a double run of Kimber 8TC (equivalent to 9Gau each) one to the woofer and one to the midrange/tweeter speakers posts. I then added another run of 12Gau Monster wire to the woofer. The entire run is 5 feet per speaker. Going from a single 16 Gau cable, this modification made the biggest difference in bass output of the 804s. Just remember that the 802s need a lot of current to function well (they are hard to drive based on impedance/phase characteristics)
2) If you feel that running in is helping the system, you can face the two speakers and then wire one speaker out of phase with the other so that the sound-waves it produces are out of phase with the other and cancel each other out. Then you can turn up the volume and leave the system to burn-in for prolonged periods, e.g. throughout the night, with minimal sound pressure (volume) in your room.
Hope this helps.
