What is the reason for my speakers having an audible buzz?


My components are Audible Illusions pre-amp to dynaco-70 up-graded amplifier to Altec Valencia speakers. Inter-connecting cables are MIT.
When I touch the MIT plug-ins at the amp, the buzz through the speakers goes away. Is this a grounding issue or do I have to have the interconnects re-done? I don't get it. Could anyone offer an explanation.  James

Most likely it’s the insulation washers around the rca connectors. If the rca connector comes in contact with the chassis you get a buzz. When you touch the barrel of the cable you are reseating the washer and the buzz goes away. Double check by trying a cheap rca cable and see if the same thing happens. If not, it could be the MIT cable.
