Hi, I have a set of JBL ceiling speakers. I used to use them via an apple airport express or extreme (cant remember which one) the apple device has a 3.5mm minijack output which connects to a Technics Hi Fi amplifier (old school stack system type) The speakers are hardwired to the amp. I could use itunes on my imac or ipad to play music via a wireless connection to apple airport express. My apple airport express has finally stopped working after 14 years so now cant use the speakers at all. So my question is, can any one recommend another more present tech device which can wirelessly connect to my ipad / imac and hardwire to speakers with a built in amp? Would rather get rid of Technics amp as it is large and us not used for any other inputs (cd radio etc) I do not want to replace the speakers either for wireless ones.
