To be honest, it's already done. It's in transit as I sit here!!!!! I picked up a used one. I'm going to do some side by sides vs. my 3805 and see if what I think right now, holds true in a week or so when the HK arrives. If it does, the 3805 is gone and will live with the 630 until such time as I can swing the AVR-7300 or whatever the newest model is they have out in a month or so from now.
