I had the same problem with a C22 pre amp and Tara Labs cables. Mac said there was nothing wrong with their jacks and that there was no upgrade either. I soldered in a new jack and use supports like those described by Bob Bundus.
McIntosh MR71 Cable Binding Advice
I love this tuner but it lacks the jacks to handle today's heavy cables. I've been using a set of Cardas interconnects and wound up with a cracked solder connection. The Cardas plugs grab the jacks with a death grip and then there's the cable weight.
Has anyone modified the RCA jacks or can anyone recommend a suitable cable?
