I have an older Harman Kardon 3490 amp (120 RMS per channel) hooked up to a pair of Axiom M60 speakers and an EP350 subwoofer. It's a great setup, but lacks bluetooth connectivity so I can't stream from Apple Music. While I usually use a CD player, having Bluetooth as well would add a lot. Does anyone have any ideas of how to add this? I tried a cheap Esinkin Wireless Bluetooth Audio Adapter but it never worked well. I could sell the HK amp and buy a new amp with built-in Bluetooth, but want to investigate other possibilities before going that route. Any suggestions? Thanks.
