concedring there is no receiver
Well that's your problem because this BOSE needs amplification.
This is stereo, so any old receiver sitting in the attic? parents don't have one in theirs? It doesn't need anything fancy, ANY old stereo receiver, amplifier will do, and for the optical, a TOSLINK TO RCA CONVERTER (inexpensive).
U mention no budget, or sonic expectation.
