Sorry to hear about your situation.
If I was presented with this situation I would find good high end dealer and trade in all your old system components and buy the very highest level you can. Storage at this time of life makes little sense... I'm 73. Buy buying up you will get more from your old equipment and will get a really high quality one box... would two do it? Linn Klimax + amp.
What part of the country do you live in?
