You are going to hear stories on both sides of this issue, which is to be expected on an open forum like this. Beware of people with their own agenda that might not be as objective as what you are looking for. The smartest thing you can do is to find a pair used, try them in your room and see how you like them. It would also not be a bad idea to try to talk to Duddleston - it can be done - and ask him your questions.
I have had a pair of 20/20s over 5 years now and a pair of Whispers for three and have had no speaker problems whatsoever.
You are also correct, the room treatment is very important and should absolutely be addressed as early on as possible. My room definitely changed with treatments, for the much better. Hope this helps.
