You can open up the Quad 909 and unsolder these strange binding posts and install conventional/cardas binding posts to take spades. I did this in my own unit, and it took one hour. It does make me wonder regarding differences in expensive/exotic speaker cables when internally the output board to binding post wires are some inferior grade wire albeit a short run.
Need help re Quad 909 Binding Posts
I would like to replace them but the shop I have used locally (ACI in the metro Washington, DC area) does not want to take on the job. Any suggestions for shops in MD or VA suburbs of DC, or in DC? (The posts don't take anything other than bare wire very well, and even that method of connection gives me pause, because the holes in the posts do not go all the way through.) Thanks!
