Don't worry Bob, it will all be good. The only problem comes when you start to tinker and calibrate too much and then it becomes a never ending quest.
You should be more than happy with everything you're getting. Take your time to just set it up, play with it, get familiar and then do a basic calibration. If you're happy take a break and enjoy it and then when you have time or interest tweak a little more.
You should be ready for the 500 and ensure all knick knacks are secured. I had one originally and it was crazy how much it put out and how much it still had left over. I ended up returning it for a couple reasons but the main one was the cost over what I got my HSU VTF3-MK2 for and how well it performed for the price difference in MY room.
