My comment is as follows:
When you become elderly, do you also plan on buying a stove, or a washing machine which is easily moved? I would say to buy something reliable that you like a lot, and keep it in one spot.. maybe get a rack with an open back to keep inputs accessible. This isn't portable audio here, there's no need to be moving things around on a regular basis. Even tube amps can sit in one sport for many years and just work.
I already have speakers I need help to move, I can't see that changing any time soon
