I’ve used a little Belkin H81 with my Bose wave for years in just that way. Works like a charm. The Belkin was dirt cheap and it still sounds great. Connectivity is better from phone than computer though. I suspect there are any number of little Bluetooth receivers that will work including some hifi types that would be better but I’m not sure it would make much difference. The magic of the Bose unit is in the folded horn construction, not any hifi circuit magic I think.
