Loftprojection - I too was trying to decide on the best location for the GR Research logo. Finally decided on locating it in the center,about 1-1/2 inches above the base plate. I think this location looks the best.
Research Audio - Presently using a Parasound P/HP-850 preamp and HCA-1000A power amp to drive the AV-3's. Also,using a Onkyo DVD/CD player.These components work very well with the speakers.
