Currently using Lofgren A with an AT33 PTGii as well. On a side note, I found the cause of the bright metallic sound that I was getting and it wasn't related to the cartridge plate. It's embarrassing to admit but it was a Hifi Tuning Supreme fuse in my tube phono pre. Took it out and put the stock fuse in and I'm finally hearing wonderful music, all is well in the world once again.
