Just an update:
My parents and I went to 2 places to look at the machines in mind. We went to a big box appliance wholesale to see the Miele W3033, but they didn't carry that model, just the Novotronic W1612. The drum of the machine was SMALL; there's no way that you can put a Queen sized fitted sheet in there, let alone a King size! I think the W1612 and W3033 have the same drum capacity, so I would assume that the W3033 would have the same small drum. The salesperson was trying to persuade us that the Miele and other European machines were "crap," and Samsung would be a wiser and better choice. The Korean set was very well-priced too, at $1200CAD for the washer (4.3 cu.ft drum) and the dryer. We knew what was "crap" so we thanked the salesperson and headed to the Speed Queen/Huebsch dealer.
At the SQ dealer there was an Imperial Series Stainless Steel washer/dryer set at the front door. The price of the set was shocking; $2999 for the washer and $1999 for the dryer. The drum of the washer was quite a bit bigger than the Miele, but still small compared to the Samsungs and Maytags. The salesperson looked very honest (compared to the one at the big box store), so I asked her if a King-sized duvet cover and a fitted sheet could be washed in one load. She said no, and kindly told us not the get the FL for one simple reason: the knobs and controls are electronic, and will have problems after 5 years (just right after the warranty expires, of course, LOL). Quite a few of her customers complained that a $3000 washer stopped working after 5 years (i.e., people can accept a Korean machine breaking down in 2 years, which cost $700). She recommended the toploaders, where the switches and timers are still mechanical. And for comparison, she also showed us a 2-year-old Samsung that was heading to the dump field, and a Whirlpool. Both of those machines were made almost entirely out of plastic, including the drum. The stainless steel was just a thin piece of metal "glued" on to the plastic drum to look like a true metal unit.
In conclusion, after looking at our 2 top choices, both didn't suit our needs very well. Our top priority was to wash the King-sized bedding in one load, and none of the machines could do that. We could go back to a toploader, but the Huebsch TL unit didn't look convincing enough that washing our clothing in it would make them last any longer than in our current machine, as the Huebsch TL has an agitator with threads around it (think huge bolt in the middle of the drum). Hopefully there will be more FL from Miele with bigger drums, and wait for the free 10-year warranty promotion to show up (we just missed it). For now, I'll continue to do more research and learn more about the technology here, but stop looking at machines in person.
