Thought I would revive this post.
This was the post so full of information that I've lurked on the AVS forums ever since reading it. The amount of solid information and input on this forum is usually nothing short of amazing.
My XR55 is still doing what it's supposed to do. When upgrade time comes I think I'll hang onto it and move it to garage duty.
I thought I had registered years ago to thank people for this thread, but I'm not seeing any posts under login names I would have likely used. So a belated thank you to all that contributed... awesome thread!
