Don't push down on the reamer too hard, take slow even rotations, and if it is chattering on the end grain ease up on the downward pressure. Clean out the scrapings regularly, and check the amount of cut. Maybe the blade needs to be advanced a little to take a deeper bite. Too deep a bit will cause chattering. I believe Elia's newer reamers have a screw adjustment for depth of cut. Check to see the reamer blade has a burr on it, it is actually a scraper and needs a burr to work optimally.
Stick with it and I believe in the end you will find the Elia type reamer is more than satisfactory and reasonably fast. I think your idea of trying to go from a 7 degree to a 6 will be a big problem on your first seat, but you may find that an electric drill solves one problem. You run the risk of having too big a hole before you know it and will have to make a new seat out of softer wood.
You don't say what wood you used for the seat, but if it is too hard to ream with a properly adjusted Elia reamer, you will really enjoy carving the seat!
