I played all three Emeralds (unplugged) for Joan today... she and I agree: the X20 has the biggest sound, then the X10, then the X7. When I asked her which she preferred to listen to, she said, "The X10 - plugged in."
For closure: the dryer repair is complete and it is as good as new. I have taken the Blonde out on the boat several times, because the weather is back to gorgeous again. Alas, the boat engine is having some fuel delivery issues - we pulled it out today and will take it to the dealer in the morning. Could I change out a fuel pump (assumption that is the issue)? Yep, but it is under warranty and they won't just give you the part to replace yourself.
