Congratulations. That is a great rack, and you will be impressed by it's sonics. I also have a four shelf Rosewood Samson v.3 rack, with the bottom shelf 4", and the other 3 shelves at 2". I ordered the 48" steel bars to allow more spacing, since my two Pass Labs x600.5 amps on the bottom generate some heat. I also have a 5 shelf Samson v.2 with 60" rods for the HT/surround system.
