Hey Doug.
After re-reading this thread after two months, here's what I think... (You may have already bought the machine, but I just should get my opinion out there..)
I have determined that most likely what you want is a smaller capacity machine. The larger capacity machines put more stress and pressure on the floor and would cause more noise, vibration and shaking, even with Samsung/LG VRT.
Unfortunately, as a compromise, washing anything king size would probably require a trip to the laundromat, where a larger, better suited machine will do the job. How often do you see yourself doing a load of king-sized items anyway?
I believe that the Asko W6903 would most likely be the most suitable candidate for what you are looking for in a washer/dryer. If the machine can handle a 2000 RPM spin speed without jumping around and killing someone, chances are, it would be lot quieter if you used a spin speed that's half that.
Keep in mind that a lot of European designed machines are designed to be used in a Kitchen, so they're supposed to be quiet. Whereas a lot of North American machines are designed to be used in a basement with a concrete floor.
If you do make a decision, post pictures and videos!!
