Originally in this thread I was seeking advice on how to make my ancient wired hifi system more flexible by allowing me to listen to my C D collection in other rooms in the house. And may be even use streaming services. Since then I have been following threads broadly dealing with my original dilemma. Unfortunately, most of the high tech stuff I read only succeeded in scrambling my poor brain. So, in an attempt to make some progress I opted for a quick , cheap and easy solution. Not one, I think, that will meet with the approval of any HiFI experts out there. What I did was connect my Pioneer CD S 802 player to my Pioneer A400X amp and then connect a cheap AV:link 2-in-1 Bluetooth Transmitter and Receiver to the Tape output on my amp and finally, via Bluetooth, to a JBL Flip speaker. Well, it works, after a fashion! At least I can listed to my CDs without taking possession of the living room. But the sound quality? Unlikely to get the approval of What HiFi reviewers! So now my question: having advanced my 21st century hifi knowledge that little bit, how can I improve on this setup? Is there something that does what the AV:Link does , but better? I'm sure there are many options for speaker improvement? Active or passive?
