Your father is in his 80’s, and he most likely will never her the difference between the Bose system and an Axiom / receiver combo. For the matter, he might not hear the difference between either of these choices and a simple clock radio. Get the Bose, let him smile, at least he made the choice himself and that counts for something, particularly at this stage of his life. .

Some people are like Slinky's, not much use however, when pushed down stairs, they make you smile.
